This aftermarket-modified Sea-Dweller replaces the standard Oystersteel case and bracelet with carbon-fiber components, creating an all-black stealth diver that weighs noticeably less on the wrist. The carbon construction displays a layered wave pattern unique to each piece, while the matte finish eliminates reflections — a practical benefit underwater and a striking visual departure from polished-steel dive watches.

The Carbon Edition Up Close: Case, Dial and Strap
Carbon fiber covers the case, bezel and crown guards with a consistent matte-black texture. The layered striations inherent to the composite material make every piece visually one-of-a-kind. At 43mm the case follows the Sea-Dweller silhouette — including the helium escape valve at nine — while cutting weight significantly compared to the steel original.
The matte black dial carries luminous indices that glow brightly after dark, and a date aperture at three o’clock completes the functional layout. A black nylon strap with tang buckle extends the tactical aesthetic from case to wrist.

Movement Options: Swiss vs Japanese
Select the caliber that fits your intended use:
- Swiss Automatic — 28,800 vph with approximately 70-hour power reserve. Smooth sweeping seconds and consistent accuracy under the demands of active daily wear.
- Japanese Automatic (Miyota) — 21,600 vph with around 42-hour reserve. Reliable and cost-effective with easy-access servicing available at independent watchmakers worldwide.
Both movements include quickset date and hacking seconds.
