Unless they no longer have a dial, then the original will be refinished...
being a omega tech, do you know what the scratch numbers on the back are?

@Archer is a lot more than an Omega “tech”, as you put it. It comes off as a bit insulting to me.

If you are referring to the number “315.164” engraved on the inside of the case back, that is the Swiss patent number (brevet) for the case construction. A lot of Omega cases made in the late 1950’s have this engraving.



The light scratch marks in the upper left quadrant of the case back are markings made by watchmakers who previously serviced the watch. They are meaningless except to the people who made them who are likely no longer with us.

See? Same patent number.

I think he is referring to these etchings.

Mrbob, they would belong to the previous watchmakers/shop that worked on it, service done to it, possibly a date, and/or signature. However, it’s not a universal language to be understood by all that see it. If you want a shot at it being deciphered, you’ll need to take it back to the hands the etched it.

Sorry no insult meant, regarding your position or ability's . I am the beginner here! I will learn . I meant the scratched and numbers marks are on the inside of my back upper left and a few other small ones around.

👍 Just so you know, he’s an independent watchmaker that is Omega certified. He’s not just an Omega tech.

Bad choice of words on my part, again sorry, as a engineer I would never be able to work on a watch just so many little tiny little bits and parts, I am use to building large electrical structures.

I have found that quite a few watchmakers were engineers in previous lives. Particularly mechanical engineers.

Isn’t @Archer a former engineer?

Never ventured in to watches, spent my years working for military designing electronics for all sorts of airplanes. 737 747 f22 f18 my specialty was power printed circuit boards high voltage and 400 amps. I can appreciate anyone who can take a complicated watch apart and put it back. With me after it was reassembled there would be parts left over. lol

He was also in the Olympics. I keep checking the Wheaties boxes at Piggley Wiggley but so far only Bruce Jenner 😁

Engineer yes, but I was not in the Olympics. Spent years trying, but timing is everything...

So I didn't make the Olympics, but my wife and I were playing tennis today, and after one rally she says:

"What are you, some kind of Ninja? Every time I think I've hit a winner, you end up hitting a winner!"

I have to say, that was nearly as satisfying as anything I accomplished as a competitive archer. 😀

Don't worry about the terminology. Just don't call me late for dinner, and we are good. 😀

As noted, the scratches in the case back are made by watchmakers to enable them to track their work for warranty purposes. This is a practice that is not longer done (by most anyway) as it is seen as damaging a customer's watch. There are far better ways of knowing if you have serviced a particular watch.

Cheers, Al
