Hi Springer,
Great post and discussions here on the dial of 1675.
One thing really puzzled me. Orchi, a forumer here, also did a thread on the dial variance of the 1675 (thread: ROLEX Ref. 1675 GMT Master Dial Variants) (
http://www.rolexforums.com/showthread.php?t=74976). What he had discussed there seems to contradict what you presented on this thread.
For example, both the threads mentioned different MK I of the 1675, although they were known by different names. The ones you mentioned were gilt and white dials whereas his were matt dials. Which came first though? or both came concurrently? or the matt dials were also known as white dials?
Would love to hear your advice and thanks in advance :)
