When I spoke to the S60 product engineer from Bullit, Pete Cunningham, at the CAT booth, I was able to give the phone a little hands-on. I noticed an SOS button on the side, but according to CAT, the final version of the S60 will not feature this. It was initially meant to send a signal of your location and message to an emergency contact, when pressed. It will be replaced by a dedicated camera button in the retail version. There’s also a toggle to switch between 2m and 5m of water depth.
