The U50 B is a precision instrument for divers and at the same time a bold statement in design. The striking matt-blue dial immediately draws the eye, signalling the highest level of professionalism and underlining the uncompromising functionality of this watch – not least thanks to the white, luminous indices and hands, which provide a perfect contrast. The result: a harmonious overall appearance with outstanding readability.
In true SINN tradition, the U50 B combines well-conceived design with technical excellence: the case and crown are made of high-strength, seawater-resistant submarine steel with the highest non-magnetic quality – a material otherwise reserved for extreme maritime applications. The captive diver’s bezel proves to be especially scratch-resistant, as it has been further hardened with TEGIMENT Technology. A practical detail: the crown is positioned at 4 o’clock to prevent pressure on the back of the hand.
Whether for ambitious dives or as a reliable companion in everyday life, the U50 B excels in every respect, as confirmed by independent testing. Its suitability for underwater use has been verified and certified by an independent Institute.
