Rotor (black): Twenty-Five 25 Jewels / Swiss Made.Rotor (black): High-Tech Escapement / Twenty-Five 25 Jewels / Swiss Made.If you have a watch with this movement, please confirm in the comments below if we have the correct ETA caliber number. As of this post, there is absolutely nothing to be found about this caliber number anywhere online. 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.Īnother Note: Although the image of the movement in the Couturier looks like ETA C07.141, it’s partially covered by the balance.

Here’s what we have so far: How to tell the difference?Īn 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: We’re doing our best to gather as much information as possible to keep this list updated. At the time of this post, there are at least four variations of the C07 (C07.111, C07.141, C07.611, C07.651, C07.811) being used in Tissot timepieces labeled Powermatic 80, but Tissot does not give clear indication which models are powered by which version. ETA C07 Base Movement:Īs mentioned above, the Tissot Powermatic 80 movements are based on the ETA caliber C07 series. This is something for hardcore mechanical watch lovers to take into consideration before spending $1,000+ on a two-tone Tissot Luxury. This doesn’t necessarily mean that the movement is impossible to adjust or service, but good luck finding parts or a watchmaker who will want to work on it. This is what Tissot refers to as their “High-Tech” escapement. Similar to the Sistem51, the Powermatic 80 laser regulated at the factory. The Powermatic 80 is not equipped with an ETAChron or other type of regulating system. This means that the PM80 beats at 21,600 bph compared to a 2824-2 beating at 28,800. Obtaining an 80 power reserve was achieved with the combination of a more efficient spring barrel and reducing the frequency from 4Hz to 3Hz. In contrast, the standard ETA 2824-2 is rated at about 38 hours power reserve when fully wound. This caliber’s claim to fame is the high 80 hours power reserve. Furthermore, ETA does not provide any official documentation on the C07 series, and these movements appear to be exclusive to Swatch Group brands only (as is currently the case for all ETA mechanical movements). The image above was one of the few available with a blurry glimpse at the base caliber number. The official Tissot site provides large images of each movement, but they do a good job of hiding the ETA caliber designation near the balance wheel. Tissot offers almost no information about the Powermatic 80 or the ETA base calibers. This caliber was announced at Baselworld 2012. It is found in various Tissot models and is based on the ETA caliber C07 series, which itself is based on the legendary ETA caliber 2824-2. The Tissot Powermatic 80 is a Swiss Made self-winding automatic movement with 23-25 jewels.
