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
• 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 two-pusher movement with a 30 minute chronograph register. Cal. 69 was produced from 1936 through 1966, with just 3,964 made in that time.
