- Subject: Info on the Valjoux 72 5
it's always a pleasure to read your watch blog.
I wish I could find the time/material to post more frequently. Hopefully I will and things will pick up.
You asked for further information on the Val. 72 theme and I checked my good old Chronograph 'bible' , the Lang-Meis, Chronographen, Armbanduhren: Die Zeit zum Anhalten (transl. : Chronographs, Wristwatches: The Time to Stop) published by Callwey, 1992, (not continued!) unfortunately only available in german. (One of the authors is Mr. Gerd R. Lang, owner of Chronoswiss, a master-watchmaker, watch-maniac and a chrono specialist .
Searching the model-tableaus I found a remark on the Valjoux 725 : 12-hour counter and flyback device..... But no photo or further description....
Wow, well that makes sense! Thanks for the info/insight!
This is the only information on this movement I ever noticed since collecting chronographs. Neither other books nor the internet brought additional information. Maybe this was a Valjoux project only which was not continued???
That's a possibility... Or it could be some firm incorporated the movement into a product without making a splash about it.
Best regards from Germany
PS: According to the named book, the Val. 71 has 14''' only. Anyone told me that the Val.71 should have been the predecessor of the Val.72. The corresponding two-subdial version to the Val. 71 is the Val. 22 (also 14''') with its successor Val.23
Good information to know! Thanks Martin! Here is an updated table:
| Valjoux 72 Family of Chronograph Movements: |

Large 15 Ligne version of Valjoux 72 (13 Ligne or just under)
| 72 || |
Basic Plain Jane Valjoux 72.
| 721 || |
"Seafarer" Tides complication in 9 o'clock sub-dial...

| 726 || |
Improved v.72 movement.
| 727 || |

| 728 || |
1 Register/Center Pinion Chrono Minute hand varitant.

Another Triple-Date model, perhaps DDM v.726?

* Note: The posting of Kohei's scan of the GP is something that throws a monkey wrench into my theory of the v.727 being a Rolex Exclusive movement, I think there is more to this movement than I know at this time.
Thank you Martin for increasing our knowledge!
