BASIS Sport -Antimagnetic- Chronometer (stop-watch) - year 1950-1959, looks and works very well for its age, . Nice and very RARE in its condition (but not perfect), at 6 o'clock barely visible a scratch on the dial, Swiss movement - the two literal buttons are to control the start and stop of the watch and can be used as a timer by pressing the button up starts the clock and the bottom button stops the clock. The dial has a rangefinder. The case is gold plated, as is the lid. The diameter is 40 mm with the crown and 38 mm without. The belt is military type I'm not a professional photographer and I hope the photos do the talking I send delivery with tracking.
