SINN 613 St UTC

Product number: 613.013

When diving, you need far more than just a watch for added safety – you need a reliable instrument that stands out for its robustness, functionality, and precision. This is exactly what our 613 St UTC diver's watch delivers, with its 60-minute stopwatch display. Thanks to its advanced technical features, it combines qualities that captivate both divers and watch enthusiasts alike.

A standout feature is the Ar-Dehumidifying Technology, ensuring enhanced functional reliability and freedom from fogging. Additionally, magnetic field protection up to 100 mT (80,000 A/m) effectively prevents magnetization, which could affect the movement's precision. Whether on land or underwater, the precise stopwatch function with its 60-minute stopwatch display – highlighted by a white sub-dial at 6 o'clock – and the diver's bezel allow for exact monitoring of dive times, making this watch an indispensable companion. As a reliable safeguard against the intrusion of dust or moisture, the pushers of the watch are equipped with our D3 system.

At the heart of this model lies a movement inspired by our chronograph caliber SZ02. This innovative precision movement was specifically developed for demanding applications. The 613 St UTC features a second time zone on a 24-hour basis – perfect for users who navigate multiple time zones.

Thanks to these exceptional technical specifications, the 613 St UTC meets even the strictest standards, tested and certified by an independent testing institute, impressively confirming their reliability. In its entirety, it embodies the pinnacle of precision and quality – crafted for challenges both above and below the water.
