In praise of Sinn's tegimented steel
Discussion
Hurrying back to my office from a meeting this morning I accidentally gave my Sinn 757 a right good bashing on the corner of a (portland stone faced) building.
I looked at the watch expecting to see it badly marked, but you know what- the only indication that contact had been made was that the bezel had been knocked out of alignment.
Very impressed.

They are definitely hard wearing.
I knock mine all the time, no marks at all. Even the big knocks that you think have done some damage - nothing.
I have scratched the bracelet, but I'm sure that would polish out if I tried or sent it off to be done.
I've caught it on door grames several times, and it just leaves a mark on frame but not the watch.

Wow, I'm impressed. Are Damasko and Sinn the only two brands that offer this level of scratchproof, toughness in a watch case? Citizen Duratec? Seiko Brightz?
The most scratch resistant watch by a country mile is the Rado V10K. Anything coated in DLC is also supposedly scratch reistant, and I've found titanium carbide coating is also extremely hard wearing.

That is a good read. I must get myself a U1 one of these days. I'm a bit skeptical of filling a watch with argon, though, as a means to replace a helium release valve (HSV). A well engineered watch, probably doesn't need an HSV, as the forces required to crack the crystal exceed the negative pressure acting on it. However, over time argon will diffuse out (due to pulling the crown out to set the time) and helium will diffuse in (assuming you're in a diving bell). Probably won't have any effect on the watch, but a valve is a better solution.Even still, for more than 99% of us, it doesn't make a difference.
The argon fill is only there to replace air so that the oxidation of oils and materials is negated. It provides a stable, inert atmosphere inside the watch. The (Viton) seals are around the shaft of the crown that should prevent the Ar from 'leaking'. Jan has got that one a bit confused - I'll dash him a line 
The dehumidifying capsule has two jobs, to absorb micro-moisture and to indicate externally when the inside of the case has absorbed micro-moisture.
An HEV is fairly redundant as, you correctly say, watches are better engineered to account for the negative pressure nowadays.

Good to know, thanks. The dehumidifying capsule has two jobs, to absorb micro-moisture and to indicate externally when the inside of the case has absorbed micro-moisture. An HEV is fairly redundant as, you correctly say, watches are better engineered to account for the negative pressure nowadays.

Finish on the watch itself is fantastic. However the finish on the strap buckle is no where near as good and is already showing noticable signs of wear, despite very light usage.
I'm not aware that Sinn do tegimented buckles for their straps. The tegimented bracelet including it's clasp on my 757 is still almost as new.I have a Sinn U1 and Damasko DC56. I really can't bring myself to sell the Sinn as it's nigh on indestructible. It's been with me for a few years through plenty of rough stuff going through hugely different atmospheric conditions - including diving, high altitudes, tropical jungles over a few years and the only thing that damaged it was when I started working for a while and accidentally exposed it to hugely powerful magnets. It did pick up two tiny pin pricks on the case when I came off a mountain bike and bounced 20 meters down a hill
