This innovation by Frederique Constant consists of a patented set of intelligent buckle and strap that can be placed on any watch. That’s why his motto is: “Turn all analog clocks into smart”.
Conceived by expert watchmakers who have already created the Horological Smartwatch, the E-Strap by Frederique Constant is the logical next step to add intelligent functionality to all watches on the market.
Fits any analog watch with handles of a width between 20 mm and 22 mm. It allows to follow the activity through activity alerts, as well as to follow the dream with intelligent sleep alarms. Thanks to the MMT-365 application, the user who carries the E-Strap on any automatic quartz or automatic Frederique Constant watch can check your activity data at any time.
