I was looking for info on how watches work (personal hang up) and found WatchRap (or was it pre-Watchrap - can't remember). There was lots of good discussion around the techie side of things then, and I also hung out a bit in Belles Lettres.
Watches themselves don't interest me too much, and I've since moved on to other things (precision clocks being one of them).
I guess my one regret is that WatchRap is closed, and all the good discussion that happened, and the amazing amount of useful info, is no longer accessible. The same goes for the Jaquet Droz forum. I was recently looking for info on something, and then realised it would have been a WatchRap discussion with Suitbert etc. Sigh...
