Pilot Chronograph 103 St Diapal Steel Watch

The Watch

Uncompromising performance, even in the most demanding conditions. This pilot's chronograph mirrors the design of cockpit instruments, true to the Sinn tradition. Topped by a domed sapphire crystal with double anti-reflective coating, the round case in polished stainless steel measures 41 millimeters in diameter, 17 mm thick, and weighs 88 grams without the strap. The case features a bidirectional grey bezel with a visual countdown function. The screw-down crown and both screw-down chronograph pushers are positioned on the right side of the case. The caseback is sapphire crystal, revealing the movement and its intricate gears.

The Dial

The matte black dial features luminescent white hands, indexes, and Arabic numerals, a date window at 3 o'clock, and three sub-dials. The small seconds counter is positioned at 9 o'clock. The chronograph's 30-minute and 12-hour counters are located at 12 o'clock and 6 o'clock respectively. This model also displays a second time zone on a 12-hour basis via a fourth hand. A striking dial that will look stunning on your wrist.

The Movement

This watch houses an automatic LJP 8000 self-winding movement. This 28-jewel caliber displays hours and minutes, seconds via a dedicated small seconds sub-dial, as well as the date and day. It features a Stop-Seconds device for time-setting accuracy to the second. It also includes a chronograph function with 30-minute and 12-hour counters. The movement runs at 28,800 A/h with a 48-hour power reserve. This watch features Diapal technology, which uses specific materials requiring no lubrification, extending both the running and lifespan of the movement. This watch also incorporates Sinn's patented Ar dehumidification technology. This technology slows down the aging process of the watch's internal components, thereby extending the movement's lifespan. It also prevents condensation from forming on the crystal during sudden temperature changes. Thanks to these technologies, this version comes with a 5-year warranty.

The Strap

Fitted with a steel bracelet with a deployant clasp, it's sure to win you over.

Water Resistance

With a water resistance of 200 meters, or 20 ATM, this watch is built for shallow-water diving. It can handle shower, bath, ocean, and pool immersion during recreational (non-professional) dives. For professional scuba diving, our Ocarat watchmaking team has hand-picked a selection of 30 ATM models available in our catalog. One last reminder before we let you go: never operate the pushers or crown while in the water!
