BASIS Sport -Antimagnetic- Chronometer (stopwatch) - year 1945-1950, looks and works very well for its age, . Beautiful and very RARE in its condition (but not perfect), Swiss mechanism - 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 one stops the watch. The dial has a Rangefinder. The case is gold-plated, as is the cover. The diameter is 40 mm with the crown and 38 mm without. The belt is Military type, beige with white sides. I am not a professional photographer and I hope that the photos are eloquent I send delivery with tracking.
