Weekend Version: There's Extra To (Watch) Life Than Metal

WE MoretoLifeThanSteel.png?ixlib=rails 1.1

For nearly the whole time I have been at HODINKEE, relating to case supplies there was metal and all the things else. It is not arduous to grasp why. Metal is affordable (you should buy a kilo of 316L chrome steel for lower than ten bucks relying on the place you purchase from) it is powerful, comparatively simple to machine, and does not have among the versatility issues that supplies like gold and platinum can have. There’s something about it that appeals to our love of the rugged individualist – metal, if it have been an motion film star, can be Harrison Ford, with a vibe of, “I do not need any hassle however when you push it you are gonna discover out I am more durable than I look.”

Nevertheless, the sheer range of tastes, events, and wishes means that there’s loads of room for different supplies and different kinds of watchmaking. An trade veteran (Swiss gent) as soon as stated to me, “You understand once I began out, there was gold and metal. In Geneva, if a enterprise government was being pushed round, the man within the entrance had a metal Rolex and the man within the again had a gold Patek, and that was it.” Occasions have lengthy since modified although, and in the present day we’re in a position to decide from amongst an unlimited number of steel alloys and different supplies.

Excessive Efficiency Gold

Gold is nice, to face an outdated adage on its head, and it’s extremely, superb for watch instances. Gold might result in corruption however in itself, it’s incorruptible – pure gold doesn’t tarnish nor does it corrode, besides within the presence of some cyanide options or aqua regia (a combination of nitric and hydrochloric acid), and if these are wherever close to your wrist you most likely have larger issues. Pure gold, nonetheless, cannot be used for jewellery or watch instances as a result of by itself it is means too mushy. The answer to that is the creation of gold alloys, but when gold does not corrode, among the metals generally utilized in alloys do, and thereby hangs a story.

Yellow gold is an alloy of gold, silver, and a few copper, and there are different alloys of coloured gold, as properly – certainly one of my favorites is blue gold, which is an alloy of gold and indium. Crimson gold, additionally known as rose and pink gold, relying on whom you ask, is an alloy of gold and a a lot increased share of copper than yellow gold. Generally there is a contact of silver in there as properly, relying on how crimson you need your crimson gold to be, however the alloy could be, and infrequently is, simply copper and gold.

Crimson gold could be very fashionable for watch instances, however it likes to do one thing that gold by itself does not, which is discolor. This occurs due to the truth that copper readily oxidizes and over time, and relying on issues like publicity to moisture or sweat, it may well develop very noticeable patches of tarnish. On a classic watch, this may be type of charming however it’s a bug, not a characteristic, in newer watches and so steps are taken by some manufacturers to scale back the possibilities of it occurring. Rolex Everose is a working example – it is a secret system (what is not at Rolex?) however it’s fairly well-known that there’s some platinum in there, and the addition of platinum is essential to retarding the chemical processes behind tarnishing. Lange’s Honey Gold is one other instance.

In 2013, Omega launched its personal in-house rose gold alloy: Sedna Gold, named after a dwarf planet within the outer Photo voltaic System (thrice additional out than Neptune) which is likely one of the reddest objects orbiting the Solar. Like Rolesor, Sedna Gold makes use of gold and copper however as an alternative of platinum Omega’s opted for palladium (a platinum group steel). The impact is much like crimson gold however to my eye, the place Sedna differs from standard crimson or rose gold is within the highlights – there’s a transition from a pinkish crimson to an virtually white which is quite mesmerizing. 


Ceramics appear, intuitively, like a horrible materials out of which to make a watch case, as a result of whenever you consider ceramics you consider issues like Meissen porcelain, Hummel collectible figurines, and damaged teacups. Nevertheless, there are ceramics and there are ceramics. There are 4 fundamental classes: Whiteware ceramics (grandma’s Wedgwood), structural ceramics, refractory ceramics (extremely heat- and corrosion-resistant), structural (ground tiles, as an example), and eventually, so-called technical ceramics. 

The final are the household used for watch instances and they’re fairly powerful. They can be utilized in conditions that problem even the most effective steels, together with protecting armor for tanks, ball bearings, jet engine turbine blades and, you guessed it, watch instances. One of the crucial widespread technical ceramics used for watches is zirconium dioxide. Pioneers in the usage of ceramic within the Nineteen Sixties and Seventies included Omega, Seiko, and IWC, and in the present day all three nonetheless use it, in addition to different manufacturers as different as Rado, Richard Mille, Chanel (the J12), and lots of others.

The fabric is way tougher than metal, and for all intents and functions, scratch-proof. The one drawback is that whereas metal or gold may dent and ding if given a tough sufficient smack, ceramics crack. Trendy technical ceramics are far more impact-resistant than the clay ceramics most of us use each day and ceramic instances have been round lengthy sufficient that in the event that they have been continuously vulnerable to catastrophic failure, I believe we might most likely realize it by now.


Titanium has a number of of the benefits of ceramics over metal, together with lighter weight and resistance to corrosion. Whereas ceramics merely do not corrode in any respect below regular circumstances, titanium does, in a course of known as passivation. Titanium oxidizes virtually instantly however the oxide types a floor layer that renders the majority of the steel impervious to additional oxidation. The safety is so full that titanium will not corrode even after extended and repeated publicity to seawater; you won’t suppose it however stainless steels can truly corrode, given sufficient time and publicity to issues like sweat, because the pitted casebacks of many classic chrome steel watches can attest.

Titanium was first found in 1791, however in nature it exists solely as an oxide and it wasn’t seen within the lab in its pure type till the early twentieth century. It took a number of many years earlier than an industrially sensible methodology for producing it in quantity was developed however after World Warfare II its benefits over metal in energy and lightness made it the steel of selection for a lot of plane designers – the Boeing 747 makes use of 95,000 kilos of the steel and it was used for the fuselage of the record-breaking A-12 and SR-71 spy planes

Bulgari Octo Finissimo Automatic Titanium

The primary watch to make use of a titanium case was the Citizen X-8 Chronometer, in 1970, adopted by the Seiko 600M Professional Diver Computerized in 1975. Seiko purchased itself some additional insurance coverage in opposition to injury by enclosing the case in an outer ceramic shroud. This illustrates one of many two disadvantages of titanium. Although the steel is extraordinarily sturdy and light-weight, it is also softer than chrome steel and scratches simply. The second downside is that it is tougher to machine than metal. Titanium tends to “gall” which implies that it sticks to chopping instruments, which, in the event that they get gunked up sufficient, now not lower correctly and so titanium merchandise are usually dearer than their metal equivalents. The scratching downside these days is normally handled by proprietary hardening methods – Citizen and Seiko each make in depth use of such strategies – or by creating supplies that mix the lightness and resistance to corrosion of titanium with the scratch-resistance of ceramics, like IWC’s Ceratanium. 


Bronze is an historic alloy, and doubtless the primary ever created. You get bronze by combining two mushy pure metals – tin and copper – and what you get is, quite miraculously, a lot tougher and stronger than both. Bronze was used for hundreds of years as the first steel for instruments and weapons (Homer makes use of the epithet, “pitiless bronze” to explain weapons within the Iliad) and for sculpture. 

Oris Big Crown Pointer Date

With bronze watch instances, one thing that is normally an issue is definitely a bonus: Bronze, over time, develops a patina, which, just like the titanium oxide on titanium, protects the steel beneath from additional corrosion. Publicity to water does not essentially imply an unacceptable stage of corrosion – bronze, significantly in so-called marine bronze alloys, does simply nice – even dunked in seawater. The factor about bronze patina is that it visibly darkens the bronze, it does not at all times happen evenly, and it may well generally flip an attention-grabbing and really noticeable shade of inexperienced. That is extra more likely to occur when bronze is in direct contact with the pores and skin, which is why lots of producers these days use a distinct materials (titanium, as an example) for the caseback on a bronze watch. For those who do purchase a bronze watch, you are getting a watch with a case fabricated from a fabric with a tremendous historical past, which can be very powerful and long-lasting. Simply bear in mind that the event of patina is one thing you must anticipate and luxuriate in – one other means for a wristwatch to show the passage of time. 

Carbon Composites And Carbon Fiber

Carbon fiber is the lightest materials on our listing and one of many strongest – two occasions lighter than titanium and thrice as stiff, and you discover it used wherever you must have lots of energy, however as little mass as attainable. The fabric is, because the Brits say, simply what it says on the tin: Fibers fabricated from carbon, typically with another materials added (epoxy resins, plastics) and in its uncooked type, delivered on spools or in sheets. Anyplace you need very excessive energy and the lightest attainable weight, you may have a tendency to search out carbon fiber – high-performance yacht hulls, F1 automobiles, and plane our bodies are just some examples, and carbon fiber is used extensively for sports activities tools as properly, in all the things from golf golf equipment to bike frames. 

Carbon Fiber G Shock

To say that the fabric has been extensively adopted is to say nothing in any respect – there may be hardly a model that has not used it in a single type or one other, and it is even discovered its means into actions, together with calibers from Richard Mille and Roger Dubuis. It is in watch instances that it actually excels, although, and whereas its use in actions could be very area of interest, its use in instances is, if not ubiquitous, actually quite common (a really incomplete listing contains Audemars Piguet, Hublot, Panerai, Doxa, Girard-Perregaux, Luminox, Victorinox, G-Shock, and on and on.)

Generally it is used purely for ornamental functions – there was a interval when auto sports-related watches with carbon fiber dials and inserts have been proliferating like bunnies within the spring – however whereas that will get gimmicky fairly quick, there are any variety of authentic causes for utilizing carbon fiber and carbon composites for watch instances. There’s a draw back to all the things however the one actual downside to carbon fiber is price. It’s totally arduous to machine and it is ten to 12 occasions dearer than metal – and that is earlier than you add on the extra prices from manufacturing and specialised technical expertise. And for some of us, carbon fiber feels too gentle – typically we wish a bit of extra heft in our luxurious watches. However as a technical materials, in lots of methods, carbon fiber stands alone.

Featured Tales

Fingers-On: The Doxa Sub 300 Carbon Aqua Lung US Divers Restricted Version

There are fairly just a few methods through which the distinctive properties of carbon fiber make it a superb materials for watch instances and maybe nowhere is that this extra obvious than in dive watches. Dive watches as a class have a tendency, for apparent causes, to be on the chunky facet and something you are able to do to lighten issues up helps take the burden off your wrist – a profit you discover much more topside than diving, which is the place dive watches spend most of their time. On this story, Doxa fan James Stacey takes an in depth have a look at a traditional design, reimagined in a cast carbon case, and along with an in depth have a look at the fabric’s advantages in a selected watch, you get loads of particulars on the position the fabric performs within the automotive world, as properly. 

The Blancpain Fifty Fathoms Bathyscaphe In Sedna Gold

The Bathyscaphe is the no-nonsense dive watch choice from Blancpain – a solidly useful design with none pointless bells and whistles which achieves the type of dignified magnificence you get from stripping away something not important. That high quality is likely to be diluted by a gold model (though gold dive watches do make sense technically) however on this case, I believe the usage of Sedna gold provides the watch not solely all of the technical benefits you get with a tarnish-resistant rose gold in a dive watch, but in addition higher aesthetics. Sedna gold is a pale sky-at-sunset gold and with its white highlights, it provides the watch an expensive really feel with out shedding the sense of purity you get from the design. 

The A. Lange & Söhne Odysseus In Titanium

The technical benefits of titanium are extensively appreciated, however for all that it brings to the desk it has not, typically, been a fabric anybody associates with high-end luxurious watchmaking. Nevertheless, that modified for HODINKEE’s Logan Baker this yr, at Watches & Wonders 2022, with the looks of one thing most surprising: a titanium model of Lange’s Odysseus. The Odysseus itself was surprising – a metal sports activities watch from Lange runs counter, ideologically, to virtually the whole historical past of the model – however a Lange in titanium would have been dismissed as an absurdity even just a few years in the past. As Logan factors out, whereas the technical properties of titanium are all current and proper, within the Odysseus they turn out to be transmuted into enhancements to the luxurious expertise and aesthetics of the watch, as properly.

A Week On The Wrist With The Ceramic IWC Tribute To 3705

One of many largest pioneers in the usage of ceramic for watch instances has been IWC, which started utilizing ceramic all the way in which again in 1986 (the ref. 3755 Da Vinci Perpetual Calendar). Within the Nineties, IWC used it for the ref. 3705, the “Keramik” model of the ref. 3706 pilot’s chronograph however the watch was not a runaway hit – solely about 1,000 have been made and now, in fact, they’re very collectible. On this A Week On The Wrist I had an opportunity to match the unique with the virtually an identical 2021 homage, which I assumed then and suppose now represents a excessive level in watch design at IWC, and can be a tribute to the historical past of ceramic instances in watchmaking. (The story can be proof that I’ve, in truth, introduced up Hummel collectible figurines within the context of ceramic instances greater than as soon as.) 

A Week On The Wrist With The Carbon Bulgari Octo Finissimo Minute Repeater

HODINKEE editors get an opportunity to test-drive lots of very totally different watches (at lots of very totally different costs) however this is likely one of the most unique: The Bulgari Octo Finissimo Minute Repeater Carbon. Right here each technical side of carbon fiber is in play – the lightness and stiffness of the case enhance sturdiness and provides the watch an aesthetic seldom, if ever, present in repeating watches and the stiffness specifically makes the case a superb resonator. Because the world’s thinnest minute repeater, you benefit from all the things you may and the Minute Repeater Carbon is a mixture of jaw-dropping conventional watchmaking, and show-stopping technical options.
