Maybe one of the various combinations will ring a bell with someone.

 

One of my SM300's has a similar markings I just assumed it was a previous owners unique marks

 

Someone out there somewhere knows what all of these mean. Food for thought.......

 

Could be an old service marking from a watchmaker.

 

I guess that's it. My ex cal. 565 Deville had a similar mark (looks like a date of service; 3/11/76?).

 

That's an absolutely amazing watch and the condition, especially of the bezel is second to none! Enjoy!

You have an exceptional 145-012. I wouldn't worry about the engraving at all. But glad to learn there are more than a few examples like this.

 

Thats a great looking watch.

 

Hard to stop looking at it. Especially in direct sunlight.
