Need opinions on the authenticity of this ref 6694

[malcolm203]

I recently purchased this 6694 and only have one doubt, the crown logo on the dial appears to be completely flat, each point does not have a raised spherical shape to it.
so far besides the reference i know it has:
78350 bracelet
557 B end links
Clasp stamping reads 1 76

Also, it appears there is wear between the lugs, the serial number is hardly noticeable, its there but illegible, this doesn't appear to be on purpose, it seems this watch was worn on a strap more than the bracelet.

Any feedback would be greatly appreciated, even the littlest time out of someones day for an opinion or reply i would be extremely grateful for.

Welcome to the Forum!

Tough call without pictures. Can you make out the first two digits of the serial number and post here? We can then check the serial range to give you an idea of the year of production. The fact the bracelet is 1976 doesn't mean the watch is, it could have been replaced along the way.
We could start there...
