Hi all, I have had thus watch for almost 50 years. It was my grandfather's watch and was bought for him on his 50th wedding anniversay. I have had it longer than he did. Along with my 2 old Omegas that belonged to my dad, thesevare my 3 most important watches. I want to know what is going on around the hour markers ... not sure it came to me with the marks around the markers. Thanks
Looks like the acquired filth of the ages, maybe a visit to the watch doctor for a probably over due service and a careful cleaning would be in order
Looks like galvanic corrosion between the gold markers, dial coating and the underlying material of the dial.
Those markers are almost certainly embossed, rather than applied, and it is a cheaper process. That type of degradation is an example.
It's been my experience that dial "cleaning" becomes a an "iffy" proposition very quickly. If you can tolerate/appreciate it, I'd suggest leaving it alone. If you can't, you can try cleaning but most likely will end up with a re-finish (from what I hear the collector's "kiss of death")
