Product Description

We take trades against any of our watches!!! We also buy watch packages!!


This is a brand new release from Sinn, first shown at the MunichTime Watch Fair in October, 2018.


Sinn has produced a number of dive watches with blue dials, the most notable of which are the now retired Sinn U1000 B and the T Series titanium watches (T1 and T2) with blue dials.

But by far the most requested Sinn divers watch with a blue dial is the Sinn U1 (and yes we have been asking for such a watch for many years), so we are very pleased to now announce the release of the new Sinn U1 B.
The Sinn U1 B case is made from the same steel that is also used in the construction of the outer hull of German submarines. The steel is procured by Sinn from a steel supplier to Emden GmbH, one of Germany’s North Sea shipbuilding yards who construct submarines from the very same steel.

Because of this special submarine steel, the case resists the effects of exposure to salt water and salt water environments and the related impacts of corrosion.

The uni-directional ratchet operated rotating bezel is also milled from this submarine steel and is Tegimented. The indices are machined directly into the bezel without the use of bezel inserts, which can corrode or come loose at deep depths.

The international testing lab of Germanischen Lloyd has tested the Sinn U1 B, and determined that the watch can be certified as water resistant to 1,000 meters. This same firm tests submarines for their ability to withstand the effects of underwater use.

Other features of this watch include:

  • Fully Tegimented bezel to increase resistance from impacts
  • New blue electroplated dial
  • Screwed bezel to prevent accidental detachment
  • Screw down crown at 4 to reduce pressure on back of hand
  • Water resistant to 1,000 meters
  • Sapphire crystal with double AR coating
  • Low pressure resistant
  • Date display at 3

This watch is fitted with a Sinn H link bracelet with locking clasp.
