Sinn DuoFlex clasp (Black hardened models with DuoFlex system)
Sinn DuoFlex clasp – Black hardened 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.
