CELEST5659 Retro Digital Watch

WARNING: this watch face needs the Calculator Complication app installed to work properly. Without it, the buttons won't respond and the calculator stays inert. Link to the app is below.

A working calculator on your wrist, styled after the digital calculator watches of the 80s. Tap the buttons and they actually compute — not decoration, not a static graphic, but real four-function math driven by the Calculator Complication app. The alarm bell glyph (ALM 🔔) opens your watch's alarm app, and the weekday indicator opens the calendar — small shortcuts to make the face useful even when you're not doing math.

Pick from 10 background colors and 10 display text colors — match the screen's "ink" to the case for a cohesive look, or contrast them for something punchier. The face works in both 12-hour and 24-hour time, with ambient and always-on display modes supported.

🎯 TOUCH ACCURACY

A note on tapping:

Watch screens are small, and the calculator buttons are smaller. Hitting them precisely takes a touch of practice.

Each button's tap region actually includes the digit or symbol drawn next to it — so the "5" button and the "5" glyph beside it are one combined target. That makes the effective center of the button sit slightly to the left of where it visually appears. A light tap aimed at the left-center of the button shape works surprisingly well.

That said, this is a watch and these are tiny buttons. Don't expect to fly through long calculations — but for the kind of math you'd do on a wrist (tip splits, quick conversions, age-of-someone-born-in-1987), it works.


📱 COMPATIBILITY

✅ Works with Galaxy Watch, Pixel Watch, and all Wear OS 5+ devices

Please note that testing was conducted on a Samsung Galaxy Watch 8. Other brands and models may experience issues, but all reported problems will be investigated and every effort will be made to resolve them.
