Hi,

I originally posted on the Modern Omega board and they referred me over to here. Since just with the few replies I received over there I can ask better questions here! I have an watch with the reference number of 2757-6 SC, serial Number 4355323 with a 355 movement that I was given by my dad and would like to know a bit more about it. Also I plan on getting it cleaned up and working so I can wear it as it works intermittently. Here are my q's:

1) I have looked at several pages / photos of watches with the same reference number and they all have 'Seamaster' above 'Calendar'. My watch has 'Calendar' but not 'Seamaster' on the dial. All of the photos I looked at have the 'Seamaster'. Is mine just an earlier version or ??

2) Any thoughts on a reasonably priced place to get it looked at / running? I am in no rush so can mail it off etc.

3) Although I like the current leather band I would like to replace it with an OEM band. Any knowledge about what the original band is like and is there a source for these?

4) Any thoughts on a rough value? I'll have to insure it if I send it off for work.

5) What is a 'bumper'? When I move my watch to wind it there is a thump...is that what the term refers to?

Here are some admittedly bad photos...sorry! Thanks in advance...

Send better pictures of the dial.

Looks like an early calendar model. Maybe the first iteration.

1) Yes, an earlier version.

2) No, as we don't know whether you live in Moscow, New Orleans, or Hong Kong!

3) Original bands won't be easy to find, but any classic leather band should work well.

4) No one can give a well-informed estimate without better photos, including one of the case back.

5) Your supposition is correct.

1) Yes, an earlier version.

The serial looks like 14*, which is pretty late, and I’ve never seen a 2757 without the Seamaster text.

Even the earlier 2627 didn’t come with “calendar” and no “Seamaster”, did it?

@ElKevvo can you send a clear straight on photo of the dial without the hands obscuring the text?

You have more experience with the model than I, but I would say that the dial is almost certainly not a redial.

Agreed, it looks fine based on those photos.. but need better ones IMO.

Thanks everyone for your responses so far, I do appreciate it! Regarding a service location, I am in the US (Texas). Anyway better camera, better photos! As far as I know the watch is wholly original and the dial should be the one that came with it.

Here are the photos...

This is a US market watch that has “Swiss” on the dial, rather than “Swiss Made”.

These did not necessarily say “Seamaster” on the dial although period advertising identified them as such.

My vote is for an original dial on your example.

Very nice pickup.

This is why I really enjoy this forum. I would had never guest that in one point the Seamaster was not on the dial. Regardless, such a cool dial.

Nothing to add but your caliber serial is 14,xxx,xxx. Not "4xxxxxxx".

Nice gift. Congrats!

PS
Btw there are some signs of rotor rubbing.

watch requires overhaul, stem, rust removed ,winding crown, replace rusty screws.,glass. dial was probably restored in the 1970s by one of a number of not very good restorers

Cool. This is the first Seamaster Calendar I’ve seen with only “Calendar” on the dial and no “Seamaster”. Nice waffle dial, too.

Thanks everyone....I really appreciate it! Cool advertisement...I looked up some others on the 'net and they brought a smile to my face with the simplicity of days passed! 'He may be a yachtsman...a sports car enthusiast...an executive on the go. You can tell him at a glance - he's wearing a waterproof Seamaster'.

I think I am going to keep the band brown leather, I like the one on it as it goes well with the gold color but it is not original and is worn a bit. Regarding servicing, any thoughts on where to send it? As mentioned, no rush. I have watch shops around where I live (DFW area Texas) but they are mostly the big chain type places. Any thoughts would be great.

Thanks again for all of the knowledge...I do appreciate it!

Looks special, May I ask some questions?@seekingseaquest @gatorcpa

How common do you find ref.2757 with “square” date?

also this one have ref.14,35x,xxx with ref.2757-6 (higher batch) so maybe not a transitional period?

Thanks

That’s a good question - I didn’t notice that. I don’t think I’ve ever seen a 2757 with a square date window, and even later 2627s had a non-square date window. But even if this dial was at some point swapped from a 2627, that wouldn’t explain the “calendar”-only text.. so maybe a service dial?

I have seen the “calendar” only text before. Maybe once or twice. Definitely uncommon.

The square date window shows up only in USA period advertising.

I suppose it is possible that the dial was swapped from a cal 353 movement. There is no way to know for sure.

The only thing consistent about vintage Omega is their inconsistency.

This has all been very helpful. Best thing I have learned? Take the back of the watch off and check the reference number etc.!! 😀

Here are a couple of other photos of the dial in more natural light. Per the various pieces of info that have been posted it sounds like the timeframe of manufacturing was in the early 50's. Would this have been something made for sale in a PX? I know sometimes that items are made with small variations for sale in the Exchanges. My dad was a Navy pilot and during that time period was flying in the Med doing ASW work.

Thanks again!

Thank @gatorcpa for your information but I am not sure that the one you show is the early version of the ref. 2627 without both “Seamaster” and “calendar” word ?

like this example from this forum, ref.2627-1 with serial no. as low as 12,527,xxx

How about the watch comes with only “calendar” word ?

thanks,
Teerapat

From my research, I also found ref.2627 without both words but with “swiss made” at 6 o’clock.
The serial no. was low as 12,529,xxx too.

I believe it was original dial but “WRIGHT ….” below AUTOMATIC was added later ?

So I believe that early seamaster calendar (date at 6 o’clock) without both seamaster and calendar can be found in both Swiss and Swiss made.
