I'm wondering if there is anywhere (online or in print) where I could find a complete or near complete guide to all of the dial variations found in vintage (Mk. I) Yacht Clubs.
Obviously there's the silver dial, blue dial and grey dial. But then there are versions with sunburst dials vs. vertically brushed, gold dials, early(?) versions that seem to have lines for the minute markers rather than dots (were these all vertically brushed?), as well as a bunch of rare versions with diamond indices, and then those weird marbled blue and green ones that have been fetching inflated prices recently...
I've seen this German article here: uhren-muser.de:8080/epaper/chronohype/chrono-4/#0
That shows some interesting unusual versions but makes no attempt to be systematic or comprehensive.
