Sinn Duoflex Retrofit & replacement – 2 case adapters: U1, U2, UX models (Tegiment Steel case)
Models with Tegiment Steel case
This special case adapter ensures a smooth fitting in all U models with a 44 mm diameter. In this way, you can attach the longer silicone strap to the watch quickly, without any tools. With this technology, an easy swap over from the ‘everyday strap’ to the ‘diving strap’ is possible. Worn on the wrist, the system can withstand the same tensile force as a silicone strap that is usually fitted to the case with spring bars.
