Sinn - U1 Automatic 1010.0001 Prototype No.1 of 6

WHAT WE LOVE:

The Sinn U1 Automatic 1010.0001 Prototype No.1 of 6 is an exceptionally rare and highly collectible timepiece, representing the very first example in a limited run of only six prototypes. Its 44 mm case, crafted from German submarine steel, delivers unparalleled strength and corrosion resistance, giving it a commanding presence on the wrist while maintaining remarkable wearability thanks to short lugs and a balanced profile.

The matte black dial exudes purposeful simplicity, with bright white hands and a red seconds hand providing superb contrast and legibility, even in the most challenging underwater environments. The unidirectional bezel is Tegiment hardened for superior scratch resistance and features precise 60-click operation, highlighting the watch’s professional dive capabilities. As Prototype No.1 of this limited series, this U1 carries a unique historical significance, making it a must-have for serious collectors seeking a rare and iconic Sinn diver.

WHAT’S INSIDE:

Powering this Prototype U1 is the ultra-reliable Sellita SW200-1 automatic movement, renowned for its robustness and precision. It offers hacking seconds and a quick-set date function, with a power reserve of approximately 38 hours. Housed within a 1,000m water resistant case, the movement ensures flawless performance under the most demanding conditions. The combination of this proven calibre and the watch’s Prototype No.1 status makes it a truly exceptional collectible, blending mechanical reliability with extraordinary rarity.
