Who was JDM? This little Cyma was bought in a clearance auction, part of a job lot. The watch meant enough for the owner to have it engraved. Why wasn't it left to a relative? Where has it been in its life? I'll never know.
I’m generally not a fan of case back inscriptions, but this one I really like. I thank you for your service, Mr. Ladwig and, by the way, you had spectacularly good taste in watches.
Don't know why this little Elgin was engraved inside with Dixon Ill. Dixon is an actual town in Illinois. But why engrave a town name instead of a person, achievement, or other milestone?
These ‘military’ style SM600’s are quite uncommon and a lot of them have a name and number engraved on the case back. Another collector recently told me he thinks many were bought by servicemen in the Far East in the mid 60’s.
