The new Sinn U1 Black is constructed from the same steel that is used on the outer hull of submarines. The steel was procured by Sinn from a steel supplier to Emden GmbH, one of Germany’s North Sea shipbuilding yards who construct submarines. This submarine steel is not only extraordinarily sea water resistant (PRE value up to 38), it also possesses the highest anti-magnetic quality.
Next, the Sinn U1 Black features a completely Tegimented case, bezel, crown and case back. Standard steel used by most watch companies has a hardness of between 200 and 240 HV (Hardness Vickers is a common scale used to measure material hardness). The Tegiment layer on this watch in combination with the PVD coating has a hardness in excess of 2,000 Vickers which is more than nine times harder than standard steel.
