Trying to find more information on this watch. It belongs to a friend of mine and we both are doing research. Given to him from his grandfather who picked it up during WW2. The back is plain. No markings. Thank you.
Are the dial numerals luminous or printed / painted ? Hands are correct, I guess. But should match the dial. Nice example! Kind regards. Achim
This trend of people coming here with outstanding, inherited watches is one trend I approve of @GVillage - have a look at this google search for more info: https://www.google.com/search?hl=da.....1ac.1.34.heirloom-hp..28.9.2438.wYohYRHc1r0
Nice 33.3. Very valuable watch. Make sure to find a competent watchmaker and let nobody else touch it (especially no Omega boutiques or mall based battery changing units...)
@GVillage your friend might care to know that when Joe Public posts a Dad / Grandad / Uncle / Other type watch here, 90% are damaged, redialled, composed of parts from different watches, have very little commercial value or are just plain boring. 9% vary from decent enough to very nice indeed. 1% are exceptional and this one falls into that category.
The serial number is the place to start. It will be on the movement, so you won't be able to see it unless you open the case back. Don't do this if you're not familiar with case back opening - not worth damaging this beauty! When you find a good watchmaker to service it, they can take a photo of the movement and record the serial number for you. Once you have it, you can use one of several online serial number indexes. My guess would be that this is ni the 9,000,000 to 10,000,000 range. Omega also has an archives service. You provide them with the serial number and reference number, and they (if the watch is in their records) will tell you the date of sale and the country it was shipped to.
