Features
Date
A feature that displays the current day of the month, typically in a small window on the dial, commonly placed at the 3 o'clock or 6 o'clock position.
Chronograph
A watch with a built-in stopwatch function that allows you to measure elapsed time in addition to its regular time-keeping functionality. It often includes a start/stop button and a reset button.
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.
200 meters
A dive watch with water resistance up to 200 meters, suitable for swimming, high-impact water sports, and scuba diving.
Uni-directional rotating bezel
A bezel that rotates in only one direction, typically used in dive watches to avoid accidental adjustments. It is commonly used to track elapsed time during a dive.
Lemania LWO 185 and 283 movements are a combination of an ETA base movement with a Chronograph module from Lemania. - LWO 185.30 has 26 jewels and the chronograph module is powered by a quartz ETA 955.232 base movement. - LWO 283.30 has 40 jewels and is powered by the automatic ETA 2892-2 movement. Lemania developed the 2000 module with Dubois Depraz, exclusively for Heuer. Many Heuer and TAG Heuer watches with chronograph movements in the 1980s-90s used the LWO 185/283. When Piaget/Lemania took over Heuer, they changed the deal to allow Lemania to sell the movement more broadly. It was later used on the original Audemars Piguet Royal Oak Offshore from 1993.
