Valjoux Cal. 25 is a pocket watch column wheel chronograph movement. Introduced around 1916, it was produced at least through the 1940s. It featured a six-column wheel to control the chronograph function. The chronograph used a central seconds hand with optional split seconds and a 30 minute counter. It was a single-pusher design.
Valjoux 24
Valjoux Cal. 24 is a pocket watch column wheel chronograph movement. Introduced around 1916, it was produced until 1970. It featured a six-column wheel to control the chronograph function. The chronograph used a central seconds hand with optional split seconds and a 30 minute counter. It was a single-pusher design.
Valjoux 23C
The Valjoux 23C is a “triple date” hand-winding chronograph movement in the Valjoux 72 family.
Cal. 23C was introduced as early as 1916 and produced through 1974. Versions before 1938 had a single chronograph pusher (“monopusher”) but Willy Breitling’s dual-pusher concept was added after this.
The Valjoux 23C and 72C are almost identical except that the latter adds a 12 hour counter at 6:00 on the dial.

Valjoux 72 Family
The Valjoux 23/72 family is one of the most celebrated and long-lived watch movements of all time. Originally a monopusher, the family was the premier showcase for Willy Breitling’s dual-pusher chronograph patent in the 1940s. A full calendar was added shortly after, and this movement family found its way into high-end watches from Rolex, Patek Philippe, Girard-Perregaux, Jaeger-LeCoultre, and many others. It was updated with a faster beating escapement in the 1970s and soon ended production. But the family lives on, with makers such as Panerai still celebrating the Valjoux 72.
The Valjoux 23 was a refinement of the Valjoux 22, reduced in size from 31.3 mm to 29.5 mm for the smaller watches in demand in 1916. It was soon joined by the elegant triple calendar Valjoux 23C. Both were monopusher chronographs with just a 30 or 45 minute counter at 3:00 on the dial and small seconds at 9:00.
The Valjoux 72 added a 12 hour counter at 6:00 on the dial. This was introduced possibly as early as 1938 but certainly by 1946, when the triple calendar Valjoux 72C was introduced. A moon phase display was added in 1947 in the Valjoux 88. The movements were continually updated over the next two decades, with a Breguet hairspring and appropriate regulator added, and the entire line moved to the dual-pusher design by the 1950s.
Production of the original 23/72/88 series ended in 1974, with Valjoux turning to the cam-operated 7736 for volume production. But the column wheel family was updated to operate at 21,600 A/h at that time, becoming the Valjoux 236, 726, and so on. These were only produced for a short time in the 1970s but were prized by watchmakers and continue to find their way into limited-edition watches even today.
Notable special variations in this family include the Rolex 722, Patek Philippe 1518 perpetual calendar, and more. The Rolex version of Cal. 72 used a Microstella regulator and were marked “ROW” (Rolex Werke) and known as “72 A”, “72 B”, “722”, or “722-1”. The Rolex version of Cal. 726 was known as Cal. “727”.
The Valjoux 23/72/88 are characterized by their 3-9 or 3-6-9 subdial layout, 9-pin column wheel, and distinctive U-shaped bridge visible on the back.

Valjoux 23
The Valjoux 23 is a celebrated hand-winding chronograph movement in the Valjoux 72 family produced from 1916 through 1974. It was replaced by the faster-beating Valjoux 236. Implementing Willy Breitling’s dual-pusher design with a column wheel, it remains desirable to this day. The design of the chronograph works, visible at the back, are particularly appealing.
The Valjoux 23 and 72 are almost identical except that the latter adds a 12 hour counter at 6:00 on the dial.
- Central hours and minute hands and chronograph seconds
- 30 or 45 minute counter at 3:00
- Running small seconds at 9:00
The Valjoux 23 was used by many brands, notably including Breitling, Bulova, Certina, Doxa, Enicar, Favre-Leuba, Girard-Perregaux, Heuer, Nivada, Roamer, Tissot, Ulysse Nardin, Vulcain, Wittnauer, and Zodiac.
