"NO REGULATOR:
The Powermatic 80 is not equipped with an ETAChron or other type of regulating system. Similar to the Sistem51, the Powermatic 80 is laser regulated at the factory. This is what Tissot refers to as their “High-Tech” escapement. 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 something for hardcore mechanical watch lovers to take into consideration before spending $1,000+ on a two-tone Tissot Luxury."
