Within the Powermatic family of movement's there are -thus far- three different levels;
C07.1XX; these have a synthetic escapement.
C07.6XX; these have a regular escapement.
C07.8XX; these have a silicon hair spring.How to tell the difference?
An easy way to distinguish the difference between the base calibers in Tissot Powermatic 80 models is to look at the features and/or text on the rotor:
Powermatic 80.111 (ETA C07.111)
Features: Date at 3:00 or 6:00
Rotor: High-Tech Escapement / Twenty-Three 23 Jewels / Swiss Made
Powermatic 80.111 COSC (ETA C07.111 COSC grade)
Features: Date at 3:00 or 6:00
Rotor: High-Tech Escapement / Twenty-Three 23 Jewels / Swiss Made
Note: The dial or caseback will have Certified Chronometer text, but not the rotor.
Powermatic 80.121 (ETA C07.141)
Features: Day at 3:00 or wide date at 12:00, date at 3:00 or wide date at 6:00
Rotor (black): High-Tech Escapement / Twenty-Three 23 Jewels / Swiss Made
Note: Tissot shows the caliber 80.121 as being in the Couturier (day at 12 and date at 6) as well as the PRC 200 (day and date at 3), but the calendar layout is different enough to call for different caliber numbers and the images show an ETA C07.141 base movement in the Courturier and an ETA C07.111 base in the PRC 200.
Another Note: Although the image of the movement in the Couturier looks like ETA C07.141, it’s partially covered by the balance. As of this post, there is absolutely nothing to be found about this caliber number anywhere online. If you have a watch with this movement, please confirm in the comments below if we have the correct ETA caliber number.
Powermatic 80.601 (ETA C07.111)
Features: Date at 3:00 or 6:00
Rotor (black): High-Tech Escapement / Twenty-Five 25 Jewels / Swiss Made
Powermatic 80.661 (ETA C07.651)
Features: Open escapement at 12:00
Rotor (black): Twenty-Five 25 Jewels / Swiss Made
Powermatic 80.811 (ETA C07.811)
Features: Silicium hairspring, date at 3:00
Rotor: Silicon Balance Spring / Twenty-Five 25 Jewels / Swiss Made
Powermatic 80.811 COSC (ETA C07.811 COSC grade)
Features: Certified Chronometer, Silicium hairspring, “Si” logo near the balance wheel, date at 3:00 or 6:00
Rotor: Silicon Balance Spring / Chronometer / Swiss Made / Twenty-Five 25 Jewels
Plastic Parts:
There is confusion about whether or not the Powermatic 80 movement uses plastic parts (similar to the Sistem51). First, it’s important to acknowledge that there is more than one Powermatic 80 caliber. For example, The Tissot Luxury line has the Powermatic 80.111 with 23 jewels and uses plastic parts. The COSC rated Powermatic 80.811 found in the Tissot Ballade does not.
