Zodiac original watch movement for Red Dot models.
The automatic chronograph ETA/Valjoux 7750 has a lever escapement, 17 jewels, mono-metallic balance, 28,800 BPH, Incabloc shock absorber. This is the one of the most popular chronograph movement the Swiss watch industry has on offer, with a unidirectional winder and a click spring construction, and you can find it in many other Swiss watches.
The key distinguishing features of the 7750 family are as follows:
Sub-dials at 6:00, 9:00, and 12:00 for chronograph hours, running seconds, and 30 minute chronograph counter, respectively
Conventional integrated center-mounted unidirectional automatic winding
Cam-controlled chronograph functions
Simple three-plate brass base:
– Calendar plate with modular components
– Main plate with off-center center wheel, hacking lever, and simple bent-spring ratchet
– Top plate with additional winding bridge
Etachron regulator and balance spring stud
The dial layout is the standard 7750 Valjoux layout with small seconds at 9:00, chronograph seconds by central watch hand, 30 minutes at 12:00 and 12 hours at 6:00. The date opening is at 3:00, with black numbers on a white disc.
The movement works well and is keeping a pretty accurate time. As for any other vintage or unused movement, a basic revision is recommended.
