How It Looks: Encased in a 42 mm titanium-and-steel case with a satin finish, the Pelagos LHD is so stealthy looking that, at first glance, most passersby probably won’t notice the unconventional placement of its winding stem. The black dial provides a stark backdrop to the distinctive calendar disk, which has been dubbed “roulette” by collectors: The even numbers of the calendar are displayed in red, while the odd are displayed in black. A beige luminescent coating on the titanium unidirectional rotating bezel matches the markings on the dial. The name “Pelagos” appears in red at 6 o’clock.

How It Works: A specially modified version of Tudor’s in-house MT5612 movement powers the LHD timepiece. Boasting a 70-hour power reserve, it has been certified by the Swiss Official Chronometer Testing Institute (COSC).

The back of each piece is engraved with a unique production number in large Arabic numerals, marking the first time Tudor has created a numbered series
