Lot 456

Swiss, Case No. 50456, Cal. VAL 69, 26 mm, circa 1930
A small vintage wristwatch with rare single button chronograph and 30 min. counter
Case: steel, push back. Dial: silvered.
Valjoux Cal. 69 DX is a compact column wheel chronograph movement. It is extremely small, measuring just 10.5”’ (23.35 mm) in diameter and was used in small-sized watches, typically measuring under 32 mm. Most Valjoux movements in the classic period were chronographs, and the Valjoux 23/72 movement family was dominated by movements measuring 13 ligne (29.50 mm) in diameter. But this family also includes a few unusual cousins: The compact 10.5 ligne (23.35 mm) calibres: 69 DX and 89 DX and the non-chronograph calibres: 78 VZSC, 89 DX, and 90 VZSCL.
Unusually for Valjoux, it has eight columns in the wheel used to control the chronograph function. It is a one-pusher movement with a 30 minute chronograph register. Cal. 69 was produced from 1936 through 1966, with just 3,964 made in that time.
