GoKawiilFitbit Air sensor can be worn under standard watch straps, users show
Fitbit's Air tracker can be combined with a traditional watch using its 18mm Performance Loop band threaded under the watch's spring bars, with the watch sitting atop the wrist and the tracker underneath. Lug widths of 18-20mm generally work, while 3D-printed adapters let owners keep their original straps and mount the removable sensor beneath them instead.
GoKawiil's interpretation of the reporting above, not reported fact.
The workaround suggests demand among users who want fitness tracking without giving up a traditional watch, a gap Fitbit's stock design doesn't fully address. Community-made adapters indicate enthusiasts are extending the product's hardware beyond its official accessories, which could inform future official strap or mounting options.
- Fitbit Air's 18mm Performance Loop can be threaded under spring bars to pair with most analog watches.
- Lug widths narrower than 18mm won't fit the stock strap; wider ones may look awkward.
- 3D-printed adapters let users keep original watch straps while mounting the removable Fitbit sensor underneath.
