And what's the base material in this instance? The blurb implies, but doesn't explicitly state, stainless.
But it is essentially the same as anodising, isn't it.
The bases material for my Sinn is stainless steel.But it is essentially the same as anodising, isn't it.
I don't believe anodising hardens the metal.

Sinns MIGHT be made of stainless, but usually coatings like that are applied to less robust materials, aren't they?. It's a sort of case hardening with decorative benefits. I'd be interested to know for sure what they are made of though.

Anodising can harden the outer surface - hard anodising is a process that does exactly that. I don't believe anodising hardens the metal.

"Tegimenting (Source):
Sinn uses tegimented 316 SS to increase scratch resistance. It forms a shell that is 4 - 5 times harder than the underlying SS. The process is called SAT12 and was patented by an Ohio company called Swagelok in August of 1998. In typical case hardening, SS is heated to near it's melting point, but with tegimentation the temperature is kept much lower. This keeps carbides (carbon bonded with other elements - particularly chromium in this case) from forming. Then they carburize (infuse carbon onto) the surface layer to increase the strength of the steel. The finished product can be dented under extreme cases, but resists scratches better than even ice-hardened steel"
What I do no from personal experience is that this watch is "well ard"
I once bashed it into the stone plinth of a building in London. Looked down expecting to see a damaged watch & all I saw was that the bezel had moved a few notches & there was some stone fragments on the case. The watch was completely unscathed but the stone plinth was slightly chipped.
Sinn also use U-boat grade stainless steel on some non-tegimented watches including the U1

We’re u boats made from stainless then? I would have guessed at plain steel painted, but I am no expert on the subject.Sinn uses tegimented 316 SS to increase scratch resistance.

Careful with that Sinn Eugene, sounds like a WMD.

Interesting articles, I did have to dig my old Zeus book out to see what 1200 Vickers was in HRC though https://watchotaku.atlassian.net/wiki/plugins/serv...
