Mechanical-watch owners have always had an awkward choice to make when fitness tracking enters the picture. Wear the watch you actually want to wear, add a second device on the other wrist, or leave the mechanical piece at home.
XBAND offers a more discreet route by moving the connected hardware into the strap, letting the watch remain a watch while the band handles activity and wellness data.
At a glance
- XBAND is a smart 20mm strap for compatible mechanical watches, launching on Kickstarter on July 8, 2026.
- The system places its sensors inside a Swiss-crafted stainless-steel module integrated with a cut-to-fit FKM rubber strap.
- Early bird pricing starts at USD 279, with replacement rubber straps priced at USD 89.
A connected strap for the mechanical-watch crowd
The appeal of XBAND is straightforward. It keeps the electronics out of the watch case and places them in the strap, where they can collect wellness and activity data without changing the character of the watch head itself.

That matters for anyone who wears a mechanical watch daily and doesn’t want a smartwatch taking over the wrist.
The system is built around a 20mm lug width, one of the most common sizes in contemporary sports and everyday watches.
It won’t fit everything, of course, but it lands in a practical zone for a wide range of field watches, divers and chronographs.

Discreet hardware and a cut-to-fit rubber strap
XBAND uses a slim Swiss-crafted stainless-steel sensor section that sits within the strap assembly rather than broadcasting itself as a separate gadget.
The result is closer to a modern folding clasp in spirit than a screen-based wearable, which is exactly the point.
The FKM rubber strap is cut to fit, so sizing is handled by trimming the strap to the wearer’s wrist before locking it into the clasp.

That close fit is more than a comfort detail, since the sensor needs stable skin contact to collect data consistently.
Four strap colours are planned, with black, white, orange and green options available.
Replacement straps without the smart module are priced at USD 89, giving owners a way to change the look without buying the entire system again.

Health tracking without giving up the watch you like
The feature set is broad for a device that hides in a strap.
XBAND tracks heart rate, sleep, blood oxygen, stress, activity and temperature, with support for more than 40 sports modes.
It also includes wellness trend tracking for blood pressure and glucose, along with women’s health tracking.

AI workout insights and recommendations are part of the package, which places XBAND firmly in the current generation of app-led fitness wearables.
The companion app is available for iOS and Android, with synchronisation for Apple Health and Google Health.
Battery life is rated at more than seven days, with charging handled by a magnetic USB-C cable in under 1.5 hours.

For anyone who already lives with the weekly rhythm of winding a long-power-reserve mechanical watch, the cadence of charging the strap once a week feels deliberately familiar.

XBAND won’t be for collectors who want their mechanical watch experience entirely analogue, and that’s fair.
For those who like traditional watches but still want daily health data, it’s a clever compromise that treats the watch as the centrepiece rather than the problem.
