Help identifying a watch

Hello Omega Forums,

I recently purchased an Omega Seamaster and opened up the case to find two sets of numbers.
Which set of numbers is the reference number?

In full disclosure, I am selling this watch on another site, and do not intend for this to be an advertisement, so I am not providing a link to the sale. This thread is purely for information gathering.

Thank you OF- I appreciate any advice you can offer.

To the mods, my apologies if this post breaks any sort of rules. P

The two numbers are 166 0208 and 366 0844.

A reference starting with 3 would include the correct Omega bracelet. A ref starting with a 1 would've come on a strap from the factory.

I guess I am confused then. It came with what appears to be the original bracelet. What is the 166 number then?

Another reference that shares the same caseback? It's pretty common.

As noted, these double reference case-backs aren't uncommon, but one can't say which reference is correct for the watch without actually seeing the watch. For example, sometimes (not in this case) the case-back is used for a center-seconds and a sub-seconds reference.

Sorry for the poor quality shot of the movement. I wasn’t able to zoom in any further without losing more quality.

No worries. It's enough to see that it does need some serious work. Have you compared your dial to other examples you've found googling the reference?

I wasn’t 100% sure which number was the reference. It appears that the 366 number shows a watch similar to one on Omega’s website from 1976, but the dimensions listed are bigger than the watch that I have. Not seeing much else online with that number.

Or chronometer and non chronometer. Is that really the correct movement in that watch?
