New update: It's not a time-piece, it's a expensive piece of crap!! it's now just over 2 years. Still looks pristine because of the excellent care I've given it. I paid $384 December 2022. Wore it ~25 times, kept it in a winder otherwise. Then last week, took it out to wear it and it's dead. Took it in for watch repair and they said it's going to be $284 to fix it. Brought it home and put it in the junk drawer. Save your money and buy something nice.
Update: it's now runing 5 minutes fast in 17 days; that's a little over 1 minute every 3 days and either I've worn it or it's been in the Winder. Still a cool watch, but sad the technology isn't more precise. It is featured in my Automatic Watch Winder which also has a very cool super quiet Japanese motor. Their description of this Tsar Bomba says "the gears on the face are not functional and are decorative only" which is fine and they do look cool, but the bottom gear featured in their display shows the gear spinning, which it does if you flick your wrist and then it lasts only for a couple of seconds and I think this makes it appear more like a Novelty; like a toy instead of a better time piece you'd expect for around $400 bucks and from the Ad, I thought it did (my mistake). So I only gave them 4 Stars because I would expect them to include that in their description as well. Not say'n it was misleading, but kinda felt that way. Either it should be part of the mechanism, or not part of the display in my opinion. Otherwise, it is a really good looking, semi-accurate and feels great on my wrist watch and I've had a few nice complements on it.
