Hey Chris! Nice to see you around these parts again.
As far as the durability of the SARB015 and 017, they feel totally bombproof IMHO. Very solid case, both crowns feel very sturdy, especially the threading on the main one. I would take my Alpinist on a multi day backpacking trip if I didn't have another watch. If I had only my 033 I would have to use the sun to find the time .
I hope that you like the Everest, and that you consider the Alpinist if you find that you are looking for something other than the Smiths!
