Senator comes to mind...searching ads...
Matches the Senator to a T except for the odd hours markers.
Tentative Senator for me, even has the brushed finished dial.
I agree with the Senator ID
Case reference # 2057
M6 on the Caseback would indicate a producton Date of 1966.
It's unclear from the images what is stamped on the Movement, possibly M7.
I too thought it was a Senator. The face on the movement kept me from making a positive ID on that. The 11AL movement date ranges mid to late 1960's
M6 is stamped on both the case and movement I have updated the photos to include close-ups that are readable.
The Patriot is the only other style that came close it has the face / manufacture time that is close, though the jewel count is not correct.
I'm good with 1966 Senator. Two ticks, as I check teh dial differences from ad (if I can find the ad).
Does anyone know the Crystal model # for this model/year ?
Linen dial even numbered - Senator "M"
Senator 'M' looks good to me.
