Fitbit Air owners have found a way to combine the screenless fitness tracker with an analogue or digital watch on a single strap, threading the watch through the Air’s band so the sensor sits on the underside of the wrist while the watch faces upward.
That clever approach works because the Fitbit Air strips fitness tracking back to its essential components, carrying no display, no buttons, and no rotating crown, which leaves the sensor chassis thin enough to sit flush against the underside of the wrist in a position that users on Reddit and Threads describe as resembling a metal bracelet clasp rather than a second device competing for wrist space.
Threading the combination requires removing the strap from the analogue or digital watch while leaving the spring bars in place, then slipping the Fitbit Air strap through those spring bars in the same manner as a single-pass NATO band, before securing the assembly so the Air sensor sits beneath the wrist.
The Fitbit Air uses an 18mm strap, which means watches with 20mm lugs will work with a small gap, while 19mm lug widths, such as those on the Certina DS Action Diver 38mm, also appear compatible, according to users who have given it a go so far.
One creator extended the approach further by printing a custom adaptor to mount a Casio calculator watch to the Fitbit Air strap, demonstrating the flexibility of the method beyond standard lug-width watches.
The current limitation of the setup centres on strap availability, as the Fitbit Air’s band options remain narrow and third-party alternatives have not yet reached the market in meaningful numbers, though Google released its own strap blueprints earlier this month to enable band manufacturers to produce near-OEM compatible options.
Google does not officially support the configuration, though the hack requires no tools beyond what comes with the tracker, making it an accessible modification for anyone who wants fitness tracking without giving up a traditional timepiece.
