Nice watch. Would love to add to the collection
The transition from PROOF to RESIST was mostly finished by 1971 and as this example is towards the end of the production run RESIST/RESIST is correct for a 1976 model.
The case looks to be in pretty good condition with the brushing still visible on the top and bottom of the case and not many dents/scratches visible suggesting the watch was looked after and that the bezel insert may have not seen too many knocks.
I could not see a side profile to gauge whether crystal is flush or protrudes from bezel.
Dial and handset look OK to me.
The movement should be a 6105b which hacks but cannot be manually wound.
Out of interest was the pressure test conducted after a recent replacement of seals?
