Breitling Chronomat, 81950

39mm military style chrono with 60 min rotating bezel.
Dates of production were 1984-1996, not sure which year this one is from.
Noticeable wear on case, bezel, but in good condition with a clean dial and crystal. Everything functions beautifully, chrono hand resets precisely to zero. Intact lume pip and smooth bezel action. Unknown service history but running well at -3 secs/day with good amplitude (see timegrapher pic). Missing bezel screw at 1 o'clock position ( these are pressed, decorative screws). Aftermarket suede leather strap.
Hard to find one of these historically important models in such good working condition, perfect for those interested in military-style, neo-vintage watches.
Watch only, questions welcomed!
