Date

Automatic Chronograph

A chronograph watch powered by automatic (self-winding) movement, featuring both timekeeping and the ability to measure elapsed time with a stopwatch function.

100 meters

A sub-dive watch resistant to water up to 100 meters, making it suitable for swimming, snorkeling, and other light water activities but not high-impact diving.

Screw-in crown

A self-locking crown that screws into the watch case to ensure water-tightness, often used in diving watches for enhanced water resistance.

Tachymeter

A scale on the dial of a chronograph that allows the wearer to calculate speed based on time and distance, typically by measuring how many seconds it takes to travel a fixed distance (e.g., 1000 meters).
