Sinn 757 DIAPAL

The Sinn 757 DIAPAL is housed in a 43mm stainless steel case with a thickness of 15mm. The 757 DIAPAL is one of Sinn’s most popular and well received offerings.

The 757 UTC DIAPAL features a Tegimented case which is five times harder than standard steel. The Tegiment layer isn’t a coating, it is a result of the steel itself being hardened via a special engineering process.

The Sinn 757 DIAPAL’s case also offers excellent protection against magnetism and is water resistant to 20 ATM. The DIAPAL movement features an oil free escapement, double Viton seals, a UV resistant galvanized anthracite dial, and a second time zone function which can be hidden when not in use.
