Built by the watch industry experts that created the Horological Smartwatch, Frederique Constant’s E-Strap is a logical next step to add smart functionality to existing watches. The ultra-small buckle extension can hardly be seen, as it is thin and covered by the leather strap. The Frederique Constant E-Strap is built on the full Horological Smartwatch Platform and its sophisticated functionality. The same MMT-365 App that accompany Horological Smartwatches is available to Frederique Constant E-Strap customers. Frederique Constant E-Straps track ACTIVITY with GET ACTIVE ALERTS as well as MONITOR SLEEP with SMART SLEEP ALARMS.

It is possible to synchronize your health data with your smartphone or tablet via Bluetooth Smart. The E-Strap can be easily recharged thanks to the small provided USB charger, where the buckle can be placed on.
Discreet yet Stylish
Unlike common silicon fitness bands, the E-Strap has a unique horological finish that preserves the authentic look of your favorite analog timepiece. The Frederique Constant E-Strap is an advanced piece of technology but it is also an elegant buckle and strap crafted under demanding watchmaking codes. When worn, the buckle merges seemlessly with the strap and becomes an extension of the watch. The E-Strap buckle is available in stainless steel, rose gold-plated and yellow gold-plated steel.
On the iOS and Android MMT-365 apps, simple and easy-to-understand graphics highlight how much one has moved and slept during the day, week, or month.
