The Valjoux Cal. 89 DXC was a compact triple-calendar hand-winding movement with moon phase. Dating to the 1940s, it was related to the Valjoux 23/72 family of chronograph movements but is most similar to the compact chronograph Cal. 69 DX.

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

Valjoux 89 Functions

Cal. 89 is a “triple calendar” movement, with day and month shown via disc through dial windows and the date indicated by a central hand. It also includes a moon phase display at 6:00 on the dial. Because it was so compact, the day and month windows are located on either side of the central pivot, at 9 and 3, rather than near the “top” of the dial at 12 as on other Valjoux triple calendar movements of the time.

  • Day of week wheel with window inside 9:00, advanced using an inset pusher at 8:00 with a deeper press
  • Month wheel with window inside 3:00, advanced using an inset pusher at 2:00
  • Central date hand, advanced using an inset pusher at 2:00 with a deeper press
  • Moon phase disc at 6:00, advanced using an inset pusher at 8:00

The moon phase advances between 16:30 and 17:00 rather than at midnight. The month does not advance automatically when the date rolls over but has to be manually advanced using the pusher.

Valjoux 23/72 Family Movements
