A diving watch must be able to withstand pressure and measure ____.

A diving watch must be able to withstand pressure and measure ____.

• A. Depth
• B. Elapsed time
• C. Temperature
• D. Pressure

Answer: (B)

Diving watches are built to endure the pressure of submerged environments while providing a simple way to track how long you’ve been under water. The essential measurement is elapsed time, which divers monitor to manage bottom time, no-decompression limits, and air supply. A rotating bezel lets you set the start time and read how much time has passed at a glance, making elapsed time the primary function. Depth is measured by a depth gauge, not a watch; temperature isn’t a standard feature on a typical dive watch; and although the watch must withstand pressure, it doesn’t measure pressure itself. So elapsed time is the best fit.
