Breitling Ref. 765 AVI 'Digital' Chronograph

Key Points from the Discussion

• The Ref. 765 AVI with a 'digital' 15-minute totalizer is a rare variant, with movement modifications being relatively simple but dial and counter disc often damaged during insensitive service work due to tiny tolerances and small aperture.
• The author's specific piece had been serviced, and while the watchmaker initially struggled with the minute counter disc, a skilled watchmaker successfully restored its function, preserving the watch's untouched dial, case, and original lume.
• The Ref. 765 series has a long history, appearing in catalogues from the late 1930s and continuing in various forms until the 1970s, making this particular 'digital' totalizer version a long-standing grail for many collectors.
• Finding a perfect example of this AVI model is challenging, with some collectors noting it was even harder to acquire than a Blancpain Air Command, and prices for these AVI chronographs have recently increased significantly.
• Historical documents from 1958 describe the dual tripmeter chronograph (15-minute counter, 12-hour hand) as intended for aviators, with the disc-based minute counter designed for easier, error-free reading during short observations like landings.
• The author plans a comprehensive photo shoot and historical overview of the Ref. 765 aviator series, spanning from the early 1940s to the last 765x Co-Pilot AVI in 1969, highlighting these often-underappreciated watches.
