sorry for the few details I have included in my post. All I know is its M7(1967) along with that it says "14KT. Gold Case" on the back with what I guess is a serial number? which is D37671. I have been searching for hours trying to find this exact model with no luck. If you have any information about this watch please do tell!!! :)
In reply to OT, I'm referring to the left by mybulova_admin
Read the description and then look at the pictures...left description is the top watch, right description is the middle watch and bottom description is the bottom watch.
