In 1990 I got a fake Rolex in Bangkok for $20AUD. After a year of it working nicely I got sick of the cheap plastic band so put a nice leather band on it that cost more than the watch. 20 years later it was still working fine but unfortunately dropped it falling down some stairs and trod on it trying to save myself. That was the end of it.

When I put a new battery in it the jeweller said it has a Japanese movement one of the best.
