Sport a Watch with the Legendary Valjoux 72 Movement

Considered by many to be one of the finest movements ever made, the Valjoux 72 is a manual-winding chronograph caliber. It is a vintage movement that hasnt been in production since 1974; several other movements are derivations of the original 72. The Valjoux 72 was employed by almost 20 watch manufacturers in numerous watch models, many of which you can find on eBay.

Variants of this movement

The Valjoux 72, itself a variant of the original nine-pillar, column-wheeled Valjoux 23 movement, features the 23s two registers, a 60-second counter at 9 oclock, and a 30-minute totalizer at 3 oclock. It has an additional sub dial and a 12-hour totalizer that appears at 6 oclock. Some successors to the 72 are:

  • Valjoux 720 - For the 720, a flyback feature was added to the original 72. A button allows the second hand to return to zero and begin counting again without the need to stop the chronograph.
  • Valjoux 721 - Many sports watch models are oriented towards divers and mariners; bearing that in mind, a complication for keeping track of the tides was added to this variant at 9 oclock.
  • Valjoux 724 - A GMT time zone complication was added to the 72 to create the 724.
  • Valjoux 726 - An improvement for added precision was made to this caliber, which operates at 21,600 Ampere/Hours, compared to the 72s 18,000 Ampere/Hours.
What vintage watch models used the Valjoux 72 caliber?

As the use of this caliber was widespread, the number of models powered by this movement is large. Well-known watch manufacturers that used the 72 include:

  • Rolex - Rolex Chronographs and the Daytona 6239 through 6241 watches used the Valjoux 72. Later Daytona models featured the Valjoux 727, a version of the 726 refined by Rolex.

Valjoux 72 vs. 7750

Beyond technical specifications such as the fact that the Valjoux 72 is a column wheel movement and the Valjoux 7750 is cam-actuated, the principal difference between these two calibers is how theyre wound. The 72 needs to be wound manually, while the 7750 is a self-winding chronograph movement.
