Sinn Introduces the U50 Dive Watch
Sinn‘s signature dive watch is the near-indestructible U1 that’s a large 44 mm in diameter. Now Sinn has unveiled the mid-sized version of the same, the U50, which offers all of the goodness of its bigger brother but in a 41 mm case. Initial thoughts I am a fan of the original U1 because it is seriously minded in its functionality, encompassing design, material, and testing. And it is affordable, making it great value for money. The new U50 has almost all of the same features and similar pricing, so it is hard not to like it.

Highly resistant to seawater corrosion and also especially nonmagnetic, the steel alloy comes from ThyssenKrupp Marine Systems, a builder of naval vessels, and is the same material used for the hull of the stealthy U212 class of submarines. It’s rated to 500 m – hence the U50 moniker – and powered by the no-nonsense Sellita SW300-1, a clone of the ETA 2892. That’s less than the 1000 m of the U1, but 500 m is still plenty – and about the same depth rating as most navy submarines. And if the submarine steel alloy alone wasn...
