Can anybody reconize the model of this Omega? It was a gift of my grandfather in 1940.

 

Hi, is there a reference number on the inner caseback?

 

yes.....9745xxx

 

Did you try to do an internet research using this number?

by the way: No need to hide that number, what makes your watch singular is the movement number 9007446

There are other watches with 9745xxx as well but only one watch with 9007446

But of course you don't have to mention it

 

This number 9745xxx is most likely the case serial#

 

That number is the serial. Seems to have the original hands too. No idea which ref this is.

 

I know the serial is unique. it was just a precaution. I've tried with internet but didn't spot a watch like this. I don't event know the caliber and I was willing to know if somebody ever had the chance to see this particular model. Knowing my grandpa, a very maniac and straight man, if the watch has been ever serviced it has been only in a official Omega retail.

 

If the caseback has an Omega logo it’s a very early wrist watch, and the correct case.

 

this is easy - it is a cal. 23.4 SC

 

1939 Omega Naiad with 23.4SC caliber, ref CK 2064.

Not sure if it's not a redial (don't see "Swiss made" under 6), but then again there is this one - https://www.njuskalo.hr/muski-satovi/omega-naiad-medicus-oglas-14683830 . Also hands look too short for this case/dial... I would like to know other opinions.

 

Well it seems very like the Naiad you pointed out. I've checked the dial and there is no mention on "swiss made". For sure my dial seems much in better shape than the one of the link.....

 

Bit the watch is so old, and for sure was used in WW2 ( he was a doctor in the british royal naby) that maybe he replaced the dial.....but I cant ask him ad he died 4 years ago

 

Sorry for the text mistakes but my T9 on my mobile phone is set for Italian....

 

Sorry, certainly not a 2064. Bezel is too thin, caseback different also, lugs have different shape.

What diameter is the case without lugs? From the pictures I would say it is a MI 2089 with 30.5mm diameter, but that's pure guessing...

 

yes its 30,5mm and I don't think its waterproof......

 

Could be MI 2089 case with movement & hands from Naiad?

MI 2089 was introduced in 1940, movement serial number suggests its from 1939, also hands look too short for this dial IMHO.

 

for sure it was given the 23 May of 1940 (Birthday gift). in the back case there is the date and name of my grandpa.

 

I am new to Omega watches, so take my opinion with big grain of salt.

I believe there is possibility that 1939 movement could be used in early 1940 watch by Omega.
Some things I am not 100% sure about:
1) Hands are too short (minute and seconds hand don't reach the rail-track). I haven't seen original Omega watches at least from that time period with hands not reaching rail-track.
2) Most watches with that style M&H hands have different seconds hand (with piled counterweight). The ones I had found which have this config, I can't be sure, that seconds hand is not a replacement. I have a 1939 Naiad watch with similar config ( https://omegaforums.net/threads/1939-omega-naiad.87464/ ), and it's original seconds adjustment spring is not original, so I am not sure that is original seconds hand. I had found couple images online with similar config, but can't be sure 100% about any of them, that it's an original config.
3) About the dial - I wonder about the luck of "Swiss made" on it (but that could be ok, according to https://omegaforums.net/threads/own...es-not-say-swiss-made-fake.46197/#post-549070 ) and also about how the number 7 looks. The only dial with similar font of 7 I have found online is https://vintagecaliber.com/products/1940-omega-cal-30t2-jumbo . You can also note that that clock has replacement crystal, it was polished, it has replacement crown, so I wouldn't trust it has original dial (and number 3 on dial is different too).

 

@deni2s serial number charts from that period are not reliable at all.
