I did notice the numbers for the date wheel are an "interesting" font lol.
The more you change it, the less it is your fathers watch. You cannot add value. I would just have it serviced so its wearable, and put on new strap (forget about finding original strap- have you ever seen/smelled 70 year old leather?). Polish or replace crystal finding original is not important. Thats what I would do. Enjoy it
Thanks, good advice. Not looking to add value, never selling it, its an heirloom. Just researching the possibility of getting parts to revitalize the watch closer to how it was when he first got it back in the late 50's. Thinking it might be a good memory of when his father gave it to him. Not die-hard on this pursuit, just exploring the idea. Did get a cool new black leather band that goes great with it, and already polished the plastic and all the gold, lightly buffed, just enough to give some shine but not remove its character and wear.
All the info I looked up for the 353 movement, connects it only to the year 1952. https://www.omegawatches.com/vintage-watches?v_watches_calibre=3017
Then I looked up how to read the serial number, it starts with 1301, and each site I see shows that the serial number is only associated (assuming by manufacturing date) to 1952. Assuming they used the movement in watches for maybe another year, but the year it is registered to seems to be 1952. Most of the information I have been seeing for the 353 (before all of the help I'm getting here) is just a spec line for a vintage watch description. There seems to be much more for the 355 than the 353.
