Sinn DuoFlex clasp (Tegiment Steel models with DuoFlex system)

Sinn DuoFlex clasp – Tegiment Steel models

All Sinn clasps are made from the highest quality materials, designed to complement watch cases.

Sinn DuoFlex offers you a high level of flexibility.
Only suitable for U1, U2 and UX models fitted with DuoFlex band – for U models with a 44 mm diameter Tegiment Steel case.

The DuoFlex consists of the two components (note this product is the DuoFlex Clasp only):

The quick-adjustment strap system
Folding clasp with strap-length quick adjustment
With the quick-adjustment strap system you can quickly swap a silicone strap for another one without any tools. For example, if you are wearing a wetsuit while diving and you need a longer silicone strap. But thanks to the quick-adjustment strap system, you can also easily switch from a red silicone strap to a black one.

With the folding clasp’s strap-length quick adjustment, you can adjust the length of your silicone strap to your desired wearing comfort. For example when seasonal temperature variations result in changes to your wrist’s diameter.
