The ETA/Valjoux caliber 7753 is an automatic cam type chronograph movement. This movement is from the same family as the caliber 7750.

7750 vs 7753

Visually (from the dial side) you should be able to tell the difference based on:

7750

  • Chronograph subdial counters located at 6:00, 9:00 (small seconds location), 12:00
  • Day/Date at 3:00

7753

  • Chronograph subdials are at 3:00, 6:00, 9:00 (small seconds location)
  • Date at 6:00

Mechanically you can differentiate between the two movements based on the setting of the date. The 7750 date sets by the crown, the 7753 set from a 3rd pusher. If you’re able to see the movement, but cannot see the caliber number stamp, remember that the 7750 has 25 jewels and the 7753 has 27.

Date Pusher

The date is typically adjusted by a pusher at 10:00. Some watch brands that use this movement opt to not include the pusher in their designs – this could be for water-resistance issues, etc. For example, Breitling labels the ETA 7753 as their caliber 23, and when used in the SuperOcean Heritage, it does not have the calendar corrector.

Hi
I would like to find the ETA 7753 used for Tudor Fast Raiser Black Shield . Basically to understand if the wheel or oscilant of the movement is always the same or can change depending the manufacture year.

A 7753 is a 7753 is a 7753. What I’m trying to say is that the Tudor Black Shield states clearly that they are simply using a “Self-winding mechanical chronograph movement, Calibre 7753” not their own movement and ETA isn’t going to change the winding direction for Tudor, and thay aren’t changing is depending on manufacturer year either. The Tudor manual itself even says “A watch equipped with a self-winding mechanical movement is wound automatically by wrist movements alone. To ensure optimum winding, wear your watch daily. Before you first use the watch or if it has stopped, you will… Read more »

Have got a Victorinox with this movement. It cost me £500 and is more reliable and accurate than other well known brands that I paid hundreds of pounds more for !! Big brand names don’t always guarantee quality x
