Received from my non-local watchmaker today with some other watches as well. Caliber 351, gold cap over stainless. Wish the dial were better, but it's original and I can't see its flaws without a loupe anyways.

This is another US-market watch with 11/16" between the lugs. Two-tone bracelet was common with gold-cap over stainless according to an Omega representative I spoke with two decades ago.

Here's hoping it keeps good time for a watch that was basically worn out.

Congrats. The two tone bracelet works well for this one. What numbers are the end pieces?

I believe it should have the bell crown rather than clover one.

 

The end pieces are #11.

As for the crown... possibly. I've not yet been able to determine with any accuracy which watch should have which crown. This is what I could get for new, not used.

Date at 6 and some great lugs...I like it!

 

Keep it? Sell it?

Stainless steel. Waffle dial. Radium lume intact. Bumper auto. Original omega signed crystal.

 

Definitely a keeper!

Should be a 353. Not 351.

 

It’s a 353 bumper.

 

I know yours is a 353, The OP wrote that his is a 351.

 

my 2627 has a 355.

is there any info as to when they switched from one movement to another among the same reference #?

 

Normally, a 355 is found in a 2757 snap case back.
If you find a 355 in a 2627, it can be a late batch that I can read on your case back 2627_8.

 

I have a 353 movement in a 2757-2 snap back case is that unusual

 

Yes, it is unusual .

 

Movement and case back photos

 

I have 6 353's movements and they range from 12.0XX.XXX to 13.4XX.XXX.

Looks like yours is a late 353 and correct for a 2757.
And unusual doesn't mean incorrect

 

I was pretty sure everything was correct,came as a full set including this box I have not seen before
