140 A S Aniversary Chronograph Watch 140.050

The Watch

Produced in a limited edition of 300 pieces, it celebrates the 65th anniversary of the Sinn manufacture while carrying forward the legacy of a collection tied to watchmaking and space history.

The Sinn 140 A S Anniversary watch stands out for its tonneau-shaped case, which gives it a distinctive, contemporary look. Made of stainless steel with a black PVD treatment, the watch pairs durability with elegance through its brushed and satin finishes. The case is 15,50 mm thick and 44 mm in diameter, lending it a substantial feel. Its 118 g weight gives it a comfortable presence on the wrist. A screw-down case back helps provide water resistance up to 10 ATM, suitable for moderate water activities. The mix of polished and satin surfaces enhances its distinctive character. A TEGIMENT treatment also significantly improves scratch resistance, helping preserve the watch's appearance over time. For added practicality, the crown screws down, further supporting its water resistance.

The Dial

This watch's dial combines clarity with thoughtful design. Its matte finish, black background, and yellow accents create striking contrast and excellent legibility. The minute track and markers are luminous, making them easy to read even in low light. The hands also have a luminous coating for greater ease of use. A date window adds everyday convenience. With its traditional analog display, this watch honors classic watchmaking while bringing a modern approach to its design and materials.

The Movement

At the heart of this watch is the SINN SZ01 caliber, based on the renowned ETA 7750 (Valjoux). This automatic movement is known for its accuracy and reliability. Its frequency of 28,800 vibrations per hour supports accurate, consistent timekeeping. A power reserve of 42 hours provides useful running time for active wearers. The movement also includes a chronograph and a hacking seconds feature for precise timing. Advanced features such as magnetic resistance and the Ar dehumidifying system help it perform reliably in a range of environments.

The Strap

This watch comes with two interchangeable bands for two distinct looks. The first, made of black stainless steel with a durable treatment, has a robust, contemporary feel. Its deployant clasp provides everyday comfort and security. The second band, made of black cowhide leather, features yellow stitching that highlights the watch's sporty character. With a 22 mm lug width and a pin buckle, it offers a simple, comfortable fit. These two bands let you switch styles to suit your mood or the occasion, from a bold metal look to a sportier leather finish.

Water Resistance

The Sinn 140 A S Anniversary's water resistance is a major advantage for those who value both style and function. Rated to 10 ATM, this watch is water-resistant to a depth of 100 meters, making it suitable for swimming or snorkeling. The screw-down case back and screw-down crown help protect against water entering the watch. It also features advanced technology, including the Ar dehumidifying system, which helps protect against moisture and prevent internal fogging to keep the dial visible in varying conditions.
