Thanks AT and Mitch for the comprehensive report. 3 questions...
1) The case & buckle are from 316L stainless steel. Any functional reason/s for not choosing Type 904L (which a brand could be using)?
2) It was mentioned on the St. Gallen website, the silicon for the straps are different from other silicon straps used in the market....
"....Its anti-shear power (to 250 ppi) exceeds any other silicon-based watch strap in the market."
What is anti-shear and how it applies to straps?
3) This watch is designed for easy disinfection with disinfectant solution or detergent.
Any tests done to verify the life of the gasket (sealing the crystal) to withstand daily disinfecting?

PuristS and NOT elitists.....
Thanks Anthony and Mitch for the "dissection" and medical review. Why isn't the Journal of the American Medical Association ( JAMA ) as much fun?....er actually the first week of April issues are a hoot! But seriously, as a doctor who used to be in critic...
Thanks, Mitch and Anthony, for a look at an unusual watch concept...
I have also heard this watch has been accepted for exhibition by the British Horological Museum for its innovativeness and application specific appropriateness. Bravo, St. Gallen and PuristSPro for out of the box thinking! TM
Love its originality
I am totally impressed and happy to see the final piece and reading all the useful info about it! Thomas, it is even so much more exciting to see and to understand ! Thanks and congrats for everything you and your team have done to the birth of this origi...
Oops sorry guys
Yes it is a boo boo on my side confused by the name and facts. Sorry Anthony and Dr Mitch, all the credits go to you both on his article write up and apology on my confusion and mistake. But I really like that watch. Where to get it ? Thanks and cheers,Li...
How is the crystal attached?
If the bezel is part of the same hunk of metal as the case, I assume the crystal is pressed in through the front and glued or gasket-fit? a
Thanks, Dr. Katz and Anthony.
Great review and fun looking watch. Question: I know that you're talking about disinfecting and not sterilizing but any thoughts on leaving it in sterilizing fluid? Thanks, Bob
Washing and Sterilization Protocol

Medical grade steel
Kong, I don't know the real reason "functionally" for using normal stainless steel 316L compared with 904. Maybe they don't see added advantage of sea-water resistance despite it's 100m water resistance rating? My suspicion is that they kept to the "medic...
Sea water resistance
Although the Rescue can be used by anyone...including sea rescue, I can't see that much call for salt-water resistance of 904 steel. Not too many clinical staff immersed in sea water for too long Regards, MTF
May a materials engineer be permitted to comment?
Type 316 stainless steel is often the default choice for corrosion resistance in seawater. However, in hot seawater (e.g. desalination plants) or under high structural loads, it does not perform as well as 904L, being more prone to pitting and cracking. T...
Fantastic report and great post, however...
It seems like the easily removable rubber strap might also easily slide off the watch by accident. Is that a concern? I've heard a story of JLC Extreme World Chrono's strap opening up by accident and slipping off the owner's wrist..
I asked Anthony that but it does not happen
I asked Anthony that and he said it did not happen. I guess they tested it well and silicon is "sticky" in it's groove. Let's see what Anthony says after more testing...... Regards, MTF
The rubber strap slipping off was not something I worried about
when I wore this watch and tested it. The friction between the strap and the case lugs holding the strap is great enough that I don't think the strap would slide off even if tugged at. Cheers, Anthony
That's true of a dry strap...
...but what if the watch and strap are wet? I'm worried too that it might slip. Could you test that please, if you still have the watch? The concept or this timepiece is great. However, I'm wary of "custom" or proprietary straps and bands in any watch. Wh...
Sorry but I don't have the watch anymore
If you want a replacement strap such as a rubber, calf leather, or stingray, you can purchase them directly from St Gallen Cheers, Anthony
We still have some PPro ABR's left if you're interested
