Tachymeter
A tachymeter bezel, subdials and a sweeping seconds hand
In the spirit of a chronograph: a tachymeter scale from 60 to 500 around the edge, a minute track, a small seconds subdial, a 24-hour subdial, the temperature, the date and a sweeping central seconds hand.

What to expect
- The tachymeter is a design — there’s no stopwatch behind it.
- The scale’s numbers stand upright rather than along the edge: they read better on 240 pixels.
How it works
- The dot on the right subdial is where the day is: midnight at the top, noon at the bottom.
What it uses
- Your city — for the weather (Open-Meteo, no key needed) — the guide
- Its words follow the screen’s language, English or Russian
- It redraws every second (a seconds hand or seconds digits)
