Here is another beauty I was Lucky to see, recently.
ZRC is not a well know brand, but it deserves some attention for their particular and very specific diving watches.
Here is a magnificient Brown dialed one.
The location of the crown, at 6 o clock, is one of its characteristics.
Don't pay attention to the insert, it seems it is not the correct one, for this reference.
If I have the time, I will try to write something about these watches, as I had the opportunity to take several other references in pictures.
