Are you sure that's a 2648? Deluxe dial and raised 'Omega'?
@cristos71
Thank you for the question.
Yes, it is a 2648. If I remember correctly, the movement is a cal.354. Sorry, I do not have the inside caseback or movement pictures. But, I do have the photo of the back, which shows a typical snap back for 2648. Two more pictures below. Hope you like it. Cheers,
AFAIK there were no 2648 pie-pans and your dial is from a Deluxe or Grand Luxe. I wouldn't expect to see an applied 'Omega' on the earliest 2648 reference either, these always have an applied symbol and printed 'Omega'
But, the subject Connie with applied symbol and "OMEGA", the dial cannot be wrong cuz the size is right for 2648. It cannot come from a Deluxe or Grand Luxe simply because the size would be smaller. Please refer to the high resolution pic of my 2648, you will find the crystal is without tension ring and the dial fits perfectly at the rim of the case. The watch was bought back to 8 or 9 years ago and is now kept at the bank. If I remember correctly the dial is 18k. Next week, I will go to the bank to take it out for a throughout check. I shall post further findings then.
