If you want someone done right... (Engraving content)

As far as I understand the older cases used a stamp for the inner text. So I did some research for stamps and ordered a custom logo stamp. The one I've got is especially used for lightweight metals like aluminium, but I like to give it a trie.
My current experience is not particularly satisfying.
1. the impact on the stamp must be so strong that I suspect the cases is warped.
2. the result got worse with the attempt I made. The stamp seems to be wearing away.
3. if the stamp is not held straight enough, the impression is uneven. There is no second attempt.

I thought it looked like it wasn't engraved, a stamp makes sense.

Probably not done by hand, maybe by a press, which would prevent it from being unevenly applied. I do (or used to do) gunsmithing, and firearms have similar looking stamped receivers from that era. It's hard to describe, but the characters look "pressed" rather than "cut":

Same idea not long ago, but still waiting for my punch... what about a hydraulic press (would be my next attempt)?

Oh wow - nice idea! I think you have to do this stamp with an press or with some holder tool, to get the stamp straight enough to the surface

on firearms they usually did rollmarks, as I remember...

Yes, use a press and have it made in a steel harder than 316L stainless that the case is in! Looks good though!

You have to heat the stamp till 1000 degrees or so and drop it in the oil.. then it should be hard enough

I'm looking forward to hearing about your experience.

I think it is hardened already you can see the colors of heat at the side of the stamp.

Yes, use a press

I tried using a vice as press. But the result was worst. My vice was not strong enough.




Today I just tried one caseback I didn't need anymore. The result was not very good. I tried a few times more but that is the best I can realize with a big hammer.

I think, it went not that bad.... but I think our approach is too ambitious! The punch-stamp routine is definitely the right one. But what, if the original stamp consists of 3 groups: ...the "MONTRES ROLEX S.A.", the "Geneva/Switzerland/Patented" & "the STAINLESS STEEL"?!

This makes sense. Three separate stamps would mean less surface area to absorb the blow, so a deeper, clearer imprint.

You could be right. But than it is impossible to place it into center without any device / guide.
By the way: if you once do your first try - use ear protection! It is so loud!

…hope my hydraulic-press stays silent BTW: ordered meanwhile 3 new punch stamps…
