This is a knock-off Tag Heuer Monaco wristwatch. It's similar to the one that Steve McQueen wore in the movie Le Mans, except that his was real, it had two sub dials, one at three and the other at nine, with the date window at 6, and it was quite a bit thinner (I once saw the original). But Tag Heuer does have one that looks like this on their website (though I don't know how thick it is), listed for £1,795. Mine cost $25 and came from China.
I don't remember when I got this, I'd say maybe 15 years ago, along with two knock-off Omegas. Both Omegas have died but this one plugs on. It's bigger and heavier than I like, but I still like to wear it regularly. I like the fact that I can read the date window without having to squint.
