How to wear a fitness tracker with a mechanical watch
Keep the watch you love and add a small tracker for sleep and activity. A screenless band can collect health data without putting a second watch face on your wrist.
You do not have to replace your watch
A mechanical watch can be something you enjoy wearing for its design, movement or history. Wanting health data does not make that watch any less useful.
A separate tracker lets each device do its own job. Your watch tells the time; the tracker records sleep and activity for you to review in an app.
Try one on each wrist
This gives both devices space and avoids their cases rubbing together. It also makes it easier to adjust the tracker for steady, comfortable contact with your skin.
If you prefer both on one wrist, check that they do not knock together, push against each other or slide under your cuff. Try the arrangement while typing and bending your wrist.
Keep the second device small
A low-profile, screenless band feels different from wearing two watches. There is no second dial competing for attention, and a light case adds less weight.
Ray weighs 7 grams and tracks sleep, heart rate, HRV, temperature trends, activity and light exposure. Its results live in the companion app. See our small-wrist guide for the fit details worth checking.
Give Ray some daylight
Ray uses light for power, so a cuff that covers it all day will limit charging. Let its surface see daylight regularly. Ordinary room lighting is not enough; here are the charging times.
A comfortable arrangement should work with your normal clothes and movements. Once you find it, you can keep your favorite watch and still collect the health data you want.
