Need help with vintage Omega caseback marks

Long story short, I have my grandfather's Omega pocket watch, which I want to pass on to my grandson. Family lore has it that the watch was a 30th birthday gift from my grandmother, which makes some sense because, based on the serial number, the watch was made in 1908, and he turned 30 in 1909. Thanks to this forum, I've been able to decipher the hallmarks, but I'm left with two questions:

>>Directly under the serial number is an "E." Can anyone tell me the significance of the E?

>>There are a number of hand-etched numbers on the caseback. Examples: 30149-1-KP; 7272GT; 7481""; 32587-1-KP. Could these have been made by the people who serviced the watch?

Thanks very much for your help!

Can you share a photo (we love photos). You are likely seeing a watchmaker’s repair marks. These are pretty much indecipherable marks watchmakers used to make a note of when they completed a service. On my 1945 Hamilton 992b there were two apparent watchmakers with long histories with the watch, one hand marked on the bottom, and a clearly different hand marked the top.

Yes, photos would be helpful. For example, are you referring to the serial number on the movement or the case? Omega PWs from that era typically had both IIRC.

The hand engraved numbers are probably from watchmakers as you inferred.

Thanks for your replies! Immediately below is a photo of the inside of the caseback (sorry if my jargon isn't correct) with the serial number and the mysterious E below it. The E must signify something, but I've not been able to determine what it is.

I couldn't capture the etchings on camera, but the E is my major question. That they were done by watchmakers who serviced the watch over the years makes sense to me.

Also included photos of the face and back. The "AS" are my grandfather's initials.

BTW, I've instructed my daughter not to give this watch to my grandson until he is at least 30 years old.

Thanks again!

The stamped numerals are silver or gold content.
The image appear to be a silver case, the funny bird symbol ? would be a Hallmark indicating Swiss assey.
If you look up the Hallmark, you can identify the year. As the Hallmark says country, English, Swiss...
A case marked Gold Filled is just that, not solid. US watch cases with gold content marked may indicate after 1924 as required by law.
Hand number scratched in are called jewelers marks for ID of who serviced the watch or an invoice number.
Should also have a manufactures stamp, unless it has been recased or a seperate company mfg the case.
This should help the curiosity.

Another note, the inner back lid has medals that Omega won in timing trials I believe for that movement.
The watch companies would have compatitions for accuracy and quality.

No problem!
If you wind up in Switzerland stop in Bien Omega museum.
Nice display, they treated us good.
