SINN U1 C HAI

Product number: 1010.0255

Included configuration

• Grey silicone strap integrated in the case

With the U1 C HAI, we are presenting a special edition limited to 300 pieces with a color gradient on the dial and a Black Hard Coating together with the specialist watch magazines Chronos and WatchTime Germany.

We only use this coating on cases that are surface-hardened using TEGIMENT technology. Only this combination guarantees the high quality of the color coating.

With its striking design, reduced displays and clear readability, the U1 C HAI focuses on the essential details. The dial, which is available in two shades of color, is particularly eye-catching and is stylishly accentuated by the harmonious interplay with the black case. The gradient from black to grey towards the center of the dial creates an exciting interplay of colors. This design is complemented by the silicone strap in grey, which is now available for the first time with a 22 mm lug.

The case of the U1 C HAI is made of high-strength German submarine steel, which is extremely resistant to seawater and has the highest amagnetic quality. The diver's bezel with minute ratcheting is captively connected to the case. This reliably prevents the bezel from jumping off, even in the event of hard impacts. All examples of the limited U1 C HAI are engraved with a shark motif and consecutively numbered on the case back.

DNV confirms and certifies the pressure resistance of the U1 C HAI up to a diving depth of 1,000 m and the temperature resistance and function in accordance with European diving equipment standards.
