This is a Tag Heuer Formula 1. I purchased it from an authorized dealer in 2019 and have used it about 50 days a year. I've only worn it in formal settings, so I haven't used it very often, and I think it's in good condition. The power reserve is about 36 hours. For the above reasons, I haven't had it overhauled yet. Returns are not accepted to prevent swapping. Feel free to make an offer or comment if you'd like to negotiate the price.
