The watch measures 39.5mm by 13.2mm with a 46.4mm stainless steel case. If you know the Alpinist, you know the functions of the 6R35 caliber movement inside—hours, minutes, seconds (with stop function), and date—and that the movement has approximately 70 hours of power reserve. There’s also that inner rotating compass bezel, which you can use to help navigate your way home. If you don’t know, in the northern hemisphere, you point your hour hand at the sun, and roughly between there and 12 o’clock on the dial should be south. Here, you can use the second crown to align that compass bezel with that southern direction and navigate.
