Blancpain’s Fifty Fathoms Bathyscaphe is now available with a blue dial combined with a Sedna® gold case.

The 43 mm x 13.40 mm Bathyscaphe case is made from Sedna® gold — the Swatch Group’s proprietary 18K red gold alloy made of gold, copper, and palladium — engineered to prevent the reddish hue from fading as it does in typical red or rose gold. Similar to Rolex’s Everose gold, Sedna® gold is also used by the Swatch Group’s Omega brand.

A dark blue sunburst brushed dial is framed by the solid gold unidirectional bezel with matching darky blue ceramic insert and Ceragold markers. Gold rectangular shaped hour and minute hands, a red-tipped gold lollipop hand, and applied gold indices — all treated with lume — indicate the hours, minutes, and seconds. A date aperture with a dark blue wheel displays the date at 4:30.

Blancpain’s in-house caliber 1315 automatic movement which beats at 4hz, has 35 jewels, and 227 total components drive the time and date functions and can run autonomously when fully wound for 120-hours (5-days) thanks to three mainspring power barrels and an efficient silicon balance spring.

In addition to a screw-in sapphire caseback and multiple gaskets, the 18K solid gold crown screws-down. Water-resistance is rated to 300 meters.

Comes with a dark blue sailcloth strap on a Sedna gold pin buckle or dark blue Nato-style strap with Sedna gold hardware. (Ref. 5000-36S40-O52A – sailcloth strap, 5000-36S40-NAOA – NATO strap) Retail is approximately $27,500.
