Dear all,
I have got a YG open face PW with black dial and Breguet numerals which should be a ref 731 (I have found a similar piece on the web in SS as a comparison which is Ref 731 according to
the archive papers).
I would like to know if the dials on this reference are black enamel (or porcelin) or if they are simply black laquered?
The extract from the archive only states "black dial" not specifying what kind of "black dial".
I do not dare to disassemble the watch for checking myself because it is near NOS and I am afraid to scratch it.
Does somebody here know about?
Thanks and best regards
erich
