Dan Wyllie wears an unidentified watch

The man on the right with the dive watch is sitting at an underground camp, relaxed, like someone who has done this enough times to be comfortable sleeping inside the earth. Dan Wyllie plays Crazy George in Alister Grierson's Sanctum (2011), one of the experienced divers on Frank McGuire's team exploring the Esa-ala cave system in Papua New Guinea. George earned his nickname. He is the crew member most comfortable in conditions that would break other people, and when the cave floods, he doesn't make it out.

A dive-style watch with a dark dial and rotating bezel is clearly visible on his wrist, worn on a metal bracelet. The brand hasn't been identified, but the style is right for the work. Stainless steel diver, decent water resistance, the kind of watch a career cave diver would wear because it was functional and cheap enough to risk losing underground.
