Case

The sporty case, with a diameter of 37 mm and a thickness of approximately 11.5 mm, is made of stainless steel. Polished surfaces, robust lugs, and two distinctive crowns equipped with the patented Compressor locking system give the watch a distinctive, technical character. The upper crown is used to operate the rotating inner ring with a minute scale, while the lower crown is used to set the time and date. Colored markers on the crowns allow you to quickly check whether the locking mechanism is open or closed.

The black dial features large Arabic numerals, applied hour markers, and broad hands coated with a luminescent substance. The unusual date window at 3 o’clock displays three consecutive dates simultaneously, while the current day is indicated by a red triangular marker. Readability is enhanced by red accents on the seconds hand and the inner minute scale. The dial is protected by sapphire crystal.

Mechanism

The watch is powered by Jaeger-LeCoultre’s in-house automatic movement, Caliber 899. The movement operates at a frequency of 28,800 vibrations per hour and provides approximately 45 hours of power reserve. It features central hour, minute, and second hands, as well as a date display. The movement has undergone the Manufacture’s proprietary “1,000-Hour Control” test, which includes checks for accuracy, power reserve, resistance to temperature changes, and the proper functioning of the complete watch.

Strap

The watch is mounted on a green rubber strap with a textured surface, which highlights the sporty character of the Master Compressor collection. The flexible, moisture-resistant material ensures a comfortable fit on the wrist, and the fastening system allows for quick and easy strap replacement.
