Finally found a perfect watch.
Well, not perfect per se, but at least satisfying my requirement.
It’s Tissot Lady Heart. It is mechanical, you can see a clockwork and it has Roman numerals. BUT it is a Tissot. And by no means it is a Frederique Constant or Breguet. It is a Tissot and I own a Tissot already. And although it is perfectly well within my budget, I wanted a real masterpiece.
The quest continues.
[EDIT - 2012] I got this watch! :D Although I admit at having been hunting for it all over Europe during my trip. Eventually I bought it in Canada. :)
