Watch Word this Week: Ceramic

Resistant to scratches, lightweight and a cool-looking alternative to metal, ceramic is the case material of choice for the Seamaster Planet Ocean Deep Black collection by Omega.

There are watch fans who believe that timepieces should tell a story, and are not averse to getting the odd scratch on their watches. For those who prefer their timepieces to remain pristine for as long as possible, however, certain case materials can help. One of these is ceramic.

Ceramic is the case material of choice for Omega’s latest launches, the Seamaster Planet Ocean “Deep Black” collection. (This follows the brand’s previous ceramic-case Speedmaster “Dark Side of the Moon” timepieces.) The 45.5mm-wide case of each of the four watches in the collection is made from a single block of ceramic, and this material is also used for the watch’s unidirectional bezels and dials.



For the uninitiated, the term “ceramic” can be confusing, and for good reason. Essentially, a ceramic is an inorganic, non-metallic solid, and this broad category includes earthenware and porcelain (materials most commonly known as “ceramics”), as well as high-tech ceramics like zirconium oxide (the material used by Omega), titanium carbide and silicon nitride.

Aside from being scratch-resistant, ceramic has other pluses that have made it an increasingly popular watch-case material: It is lightweight, hypoallergenic, and also resistant to high temperatures. What ceramic is not known for, however, is holding up well to strong impact, which makes it even more interesting that Omega has succeeded in making their new ceramic-clad dive watches water-resistant to a depth of 600 metres.

The Seamaster Planet Ocean “Deep Black” watches are available in four variants: Ceramic and Sedna gold, all-black, and with red or blue accents.
