CASE & BACK: This watchmeasures a large 39 x 44mm not including crown and is 12.5mm to the top of the flush fit crystal. The heavy all-steel case does not appear to have ever been polished and still shows its original bevels and and contrast satin-polished finish. There are very few superficial scratches and some nicks commensurate with a very lightly worn 46-year-old tool watch — Fantastic vintage condition overall. The outer part of the screwed steel back has some very light and superficial scratches but shows its original Breitling nomenclature of the period including the 1346994 serial number on the outside, which indicates a 1970 production, and correct 2010 reference–also Excellent original cosmetic condition. The inner caseback shows no corrosion and has the correct internal Breitling engraving of the era.
DIAL & HANDS: Gorgeous black dial with black printing and finely calibrated track and only the minor imperfections visible under a loupe All original Tritium luminous numbers.
CROWN & PUSHERS: Signed Breitling crown looks very clean and winds and pulls out to the time-setting position as it should. It sits tightly against the case. The two pusher caps are likewise in Excellent shape and both chrono pushers work as they should and also nice and crisply.
CRYSTAL: Large flush-fit acrylic crystal is Excellent+ without scratches and no deep marks and sits barely proud of the bezel, which I believe to be correct for this model.
MOVEMENT: Legendary Manual wind, Valjoux cal 7733 chronograph is looking bright and working well with all correct Breitling nomenclature of the era and shock protection. Watch is keeping good time with a strong power reserve and all chronograph functions are working properly and returning to zero. This is guaranteed to be the case at the time of shipment.
