Exactly like that, at one of the largest second hand dealer in HK, and probably in the world (in Champagne Court, Kimberley Street). It's a very uncommon configuration, and quite beautiful.
I've seen the most interesting Breguet Type XX models in that shop. In particular a yellow gold / white dial one that was spectacular. I much prefer your platinum / salmon dial version, though. I will ask this question again: is there any cool watch that ...
