The Tungsten Watch can be crafted by combining 10 Tungsten Bars and a single Chain within proximity of a Wooden Table and Chair. This is presumably because the player would need to sit down and work with a flat surface while constructing the watch. It is a component of the 3 Second Timer.
- When accessories are worn that cause the time, position and/or depth to be displayed simultaneously, the position is displayed at the top, with the depth in the middle and the time at the bottom.
- According to the watches, Daytime begins at exactly 4:30 AM and Nighttime begins at exactly 7:30 PM.
- Added to the game.
