Kobold Arctic Diver - Steve Austin - Hunt to Kill
The watch, an Arctic Diver "SWISS" reference number KD 832121-C was released by Kobold in 2009. These Swiss-made Kobold watches are designed for professional use by experts. Its oversized (46 mm-wide) case is crafted from surgical stainless steel and features a thick, domed sapphire crystal with antireflective coating on the inside, as well as a screw-locked winding crown and screw-locked caseback. The Arctic Diver "Swiss" is rated to a depth of 500 meters.
The Arctic Diver "Swiss" normally comes on a natural rubber strap and is shipped in a wooden collector's box but the strap in the movie looks like a custom made paracord strap. This is a band woven from one line of paracord. To make your own paracord strap, see instructions on Stormdrane's Blog or see some examples of other paracord items on Amazon.
The Skull logo on the dial was probably custom added for Steve Austin.
