BASIS Sport - Telemetru-Antimagnetic- Chronometer (stopwatch) - year 1950-1959, looks and works very well for its age, . Beautiful and very RARE in its condition (but not perfect), Swiss movement - the two literal buttons are to control the start and stop of the watch and can be used as a timer, pressing the top button starts the watch and the bottom button stops the watch . The dial has a telemeter. The case is gold plated, as is the cover. The diameter is 40.5 mm with the crown and 38 mm without. The strap is military type I am not a professional photographer and I hope the photos speak I send the package with tracking.
