Help Requested - Omega pocket watch identification and advise

Hello there dear watch enthusiasts,

I recently was given a beautiful Omega Pocket Watch from my mother, which has been in family posession from when it was first bought by my great-grandfather somewhere in the then German Reich. From what I know it was last serviced late 70s, it still runs after I carefully wound it up for only a few turns so as to check it runs but not to damage it.

I would appreciate your help with the following please:

• When was it most likely produced?
• What model / style / movement is this watch?
• Would you recommend any specific work to keep it in good condition beside a revision of the mechanics?
• Extra points if you can recommend any watchmaker you would trust this with in Switzerland.

Thank you so much for your help!

Pictures and further comments below:

Clockface with what looks like enamel and little gold pyramids as the minute indicators, I could not find another example online of this design.
There is some grease smudges and dust in it, but I could not open the front with just my fingernail and did not want to use a tool


Crown with a small mark I could not further identify also with a looking glass.


Back of the watch, the main body is roughly 50mm, the pattern around the coat of arms is nearly completely rubbed off.


Insides of the back: from what I gather the 0.800 silver mark plus the German silver mark (Half Moon and Crown).
The Serial Number is 1435353 with the letter K below it - when you open the second lid which houses the movement, there's an additional 22 stamped below that. There are multiple thin, handcarved numbers which I assume are from revisions.
The backs where both easy to open with my fingernail via a little notch.


Last but not least the inner workings, there is still quite a bit of grease in there, some mixed with dust and grime.

Hi Dan,

Thank you - based on that it's somewhere between 1894 and 1902.
Maybe someone has further insights beyond that e.g. if there were more of these built at the start or later to further date it.

And no, there is only the omega mark with some indices plus decorative engravings.

Thank you Canuck - regarding the dial, is that because there were so many versions of it during that time?
Most picture I found online have the "chequred" pattern around the clockface instead of these golden "pyramids".

Thank you so much for that extra insight JimInOz!

How would I best get the jewel count for this movement please?
Is there a specific pattern to look for or reference I can check against?

The only other number I found (apologies I forgot to add a pic of it above) - is the 22 and a K under the serial number on the second backplate above the movement. Any idea on what these might stand for please?

Thank you very much all for your help - I'll update once I've found time to go to a watchmaker for the revision.
