This ACCUQUARTZ watch appears to be somewhat unusual. The dial does not have the accutron emblem but has an unknown emblem (looks like it might be from the Luftwaff!!!) perhaps some company logo as a presentation watch. It is strange there are no serial numbers. I believe the band may be original but there is no manufactures name and only imprinted with USA.
I recently purchased this watch and was quite surprised at how pristine the watch is.
