Leonidas stopwatch

*Leonidas Watch Company* was a *Swiss manufacturer* founded in *1841* by Julien Bourquin in Saint-Imier, Switzerland — one of the same watchmaking towns later home to Heuer and Longines

* *Type:* Mechanical hand-wound stopwatch

* *Dial:* White enamel dial with black Arabic numerals; outer ring marked in 1/5-second increments up to 60 seconds

* *Subdial:* 30-minute register (upper sub-dial) for recording elapsed minutes

* *Movement:* Likely a Swiss mechanical caliber by Leonidas or Valjoux, depending on the model

* *Case:* Chrome-plated brass or steel

* *Markings:* “LEONIDAS” and “MADE IN SWITZERLAND” printed on dial

This is a *professional-grade analog stopwatch*, not a simple consumer timer — built for sports timing, lab work, or military applications.

Most likely *1950s to early 1960s*, shortly before the merger with Heuer.

* Working, but requires a service.
