Hello everyone,

I have an old Omega watch and I am looking for identification, information if it is military watch or military style only and estimate value. The dial seems to be porcelain, case is probably silver. Diameter 35-36mm
Thank you in advance for any info you might be able to provide.

Best regards
Jakub

 

Without military markings or provenance it’s not a military watch...

 

Maybe not military issued, but maybe a "used by a soldier" type watch, so called "trench watch"

The silver case is marked with the London Assay Office import stamp, .925 silver mark and a date letter mark for 1916 and the case makers stamp is AS (unknown to me).

Movement looks to me like an Omega savonette caliber (13''' SOB?) but I'd need to know the exact diameter to pin it down. Serial number of the movement dates it to about 1915/1916 and the case serial is from approx 1913/1918.

The black dial is unusual but the symbol and the fonts are correct for the period.

 

Thank you very much. Regarding doameter of the movement I will provide within few hours.
Any idea about value?

 

Something along these lines...

 

The diameter of the movement is 28mm +- 0,05mm

Crown seems to be original but I would like to confirm it because is different from this one on attached photo.

Thank you in advance.

 

Could be the rare caliber 27.9, only way is to check the main plate under the dial. The crown could be original, it often depended on what the case makers used or had in stock or it could have been replaced during a service, but it doesn't really matter as the pedantic anal preoccupation with the correct number of teeth on a crown doesn't apply to these watches, only to vintage Speedmasters .

 

Wow, good news.
Please see attached photo.

 

Hmmmm, not much to see there, just the movement number.

Can you decipher the numbers on the tail of the barrel plate?

 

It is not a number, it is "SWISS"

 

Now you can tell sth more about it? If you need more info please tell me

 

I think it's worth getting an extract from the Omega Archives.

Just send pics of the movement, nothing else.

 

Ok I will do it.

Can you confirm if it is correct link?

Regarding value, can you help me with that or it depends on what Omega will say?

 

if you need the value because you have not bought it yet, these are surprisingly cheap. the way, the lugs are welded to the silver case, makes me think, it is a pocket watch, re-soldered with lugs to make it wearable. better pictures might cleat that up. my guess is, that it is around 34 mm max without the crown. purchase value , if dial is uncracked, might be around $ 500. the hands do not look original to this watch. more like the russian replacment hands for pre 1950 watches.but, all guesses because of the lack of detail so far. kind regards. achim

 

It is my watch. Lugs looks exactly the same like in watches attached by tyrantlizardrex above. The diameter is 35,00mm. The middle and back case are one piece. Front ring/bezel is screwed.

 

Hi,
I know this is an old thread. Can someone let me know what movement was produced first.
The Omega 13 SOB or the cal 27.9 SIBN?
Cheers Russell.

 

Caliber 13''' was introduced in various iterations in 1896, 1901, 1905.

Caliber 27.96 (or 27.9) was introduced in 1917.


AJTT refers.

Doh, not 13''' F! so ignore the 1896 reference.

 

I have a Caliber 27.9(6) with a serial in 3,6xx,xxx, which dates to 1906, according to one list...

Mine also has 17 jewels.

Hi everyone,
The OP's Watch is a 13 lignes, not a 27.96. 27.96 is easy to spot because it is a negative hour setting. The onion crown is probably a replacement, Omega wristwatch from this period had a flatter model.
Black dials are unusual Indeed.
Here in a 1917 catalog :

Mine -1916, replacement crown also- says hello :
