Having the bracelet slightly loose, I'm able to slide my index finger under the clasp and push up to unlock it.It was the hardened steel. The ceramic ball bearings wore the metal down until it would open without my intervention. I am not saying it will happen to you but it seemed at the time like a design flaw for the DA-38 I had at the time. I am sure if there were issues with the clasp Damasko would have changed the design by now. But if you do open and close it a lot then just be mindful if it starts to get easier to open. That is actually not a good thing. I am not talking a very slight difference but once there is a noticeable change from the beginning of when you bought it.
Funny you say Archimede outdoor protect as that was something I got after the DA38. lol
Personally I think the design of the DS30 is about as good as it gets.
Outdoor protect is a great watch but and this is a big one for me is that they don't use the same hardened steel everywhere. It has a great Ickler case and good lume but the crown and case back are just 316l and you have to pay extra to get the hardened bracelet and the Protect bracelet is no where even near close to as cool as the Damasko. I have my issue with the clasp but there is no doubt it is a beautiful piece of custom designed kit. The bracelet on the Protect seemed like a cheap thin foreign made bracelet that was "hardened". The bracelet edges were so sharp it almost cut my wrist-no joke.
It is crazy how the cost is very similar between the two watches with hardened bracelets-Damasko is clearly an infinitely better watch in my biased opinion.
I guess this is the best compromise between best fit for bracelet and best way to unlock the clasp.
I've also read some rust issues with the hardened bracelet for Archimede OP. Think that's why it's not the default option now.
I also have experience with cutting myself from watches. Hamtun Nanok comes with bulky racheting clasp that has sharp edges. In the summer with short sleeves and pants, I was cutting myself everywhere.....not good.
So you moved on from Outdoor Protect? Just curious what your next was....
