⚠️ This watch face requires the Calculator Complication app to work. 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. CELEST5666 Retro Digital Watch puts real four-function math behind every button — not decoration, not a static graphic, but actual computation driven by the Calculator Complication app. Tapping the date and weekday indicator opens the calendar — a small shortcut that keeps this calculator watch face useful even when you're not doing math.

🎯 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 includes the digit or symbol drawn next to it — so the "5" button and the "5" glyph beside it are one combined target. The effective center sits slightly to the left of where it visually appears. A light tap aimed at the left-center of the button shape works well.
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.

🔧 Installation Help
Having trouble? We've got you covered:
- Use the dropdown menu next to "Install" on your phone to select your watch model or install directly from your watch's Play Store app.
- Updating weather data (if the watch face shows weather) may take time after installation but switching to another watch face and switching back or restarting both the watch and phone usually helps.
