Chang-Soo Lee,
Tough criteria you place on your next 'dress watch'.
Washing with water every day is very demanding but if you must...you must.
Some brands have extended the definition of 'dress watch' with models that are water resistant and with metal bracelet e.g. Audemars Piguet Extra thin Royal Oak, Piaget Altiplano Bracelet and most recently Bulgari launched the Octo Finissimo Automatic Sandblasted Trilogy (steel, pink gold, titanium).
They could all do nicely...
Regards,
MTF
