Angelus "infirmière" based on a Valjoux 22 caliber
Very special and curious chronograph. This Angelus was made for nurses, to measure breathing. It is based on a Vajoux 22 14''', columns wheel, 18'000 A/h movement.
Delma chronograph based on a Venus 170 caliber
Here above is pictured a Delma chronograph, based on a Venus 170 12 1/2 ''', columns wheel, 18'000 A/h. Many chronographs have used the Venus 170, like vintage Breitling for example. This movement is certainly not the best Venus produced. Some technical particularities reduce its reliability in time. When buying a chronograph with the Venus 170, check well the movement running in all positions. If any doubt ask for a watchmaker advice. The Delma showed here caused us some worries ! Look at the dial figures and the hands. They were all refreshed with real Tritium.
Others for fun
First line shows a very curious chronograph based on a Valjoux 7750. Very big sized, this watch was intended to be either worn or put on a desk. The one pictured is an ETA prototype which never met a big success, certainly for esthetical reasons. Note the crown and the pushers position at 12. Second line are 4 pictures about an anonymous watch based on a Venus 150 caliber 13''', columns wheel and Breguet spiral. This watch was bought in such bad condition, that we decided to "personnalise" it. Back case was so damaged that we made a big hole to fit a saphir cristal in order to see the movement. Regarding screws, it was time for our first initiation to blueing skill. Result is what you can see. It could have been much better !! Observe one browned screw. It was not steel thus this curious obtained colour. Third line, a new old stock Valjoux 7733 movement 14'''. The 7733 was produced until the seventies at many millions of pieces distributed around the world. Cam caliber, it has became more and more difficult to find. As the newer Valjoux 7750, the manual 7733 was a very reliable movement, despite its "squared" design.
