Longines Conquest Heritage 40mm
The Longines Conquest Heritage 40mm pays tribute to the brand’s historic creations while incorporating today’s watchmaking technologies. Its automatic L888 movement provides a 72-hour power reserve, while its retro aesthetic follows the codes of the original Conquests, including the 18-carat gold medallion on the screw-down case back.
Design and features
The model features a 40mm round stainless-steel case, an anti-reflective treated sapphire crystal, and a lacquered dial available in black, silver, blue, or green. Applied indices and luminous hands with Swiss Super-LumiNova® enhance readability while maintaining the collection’s distinctive vintage elegance.
The variants offer your choice of:
- a stainless-steel bracelet with a double safety deployant clasp with micro-adjustment,
- or a leather strap (calfskin or alligator, depending on the version) fitted with a classic buckle.
Movement and performance
The watch is powered by the Longines automatic caliber L888 (Automatic Mechanical), oscillating at 25,200 alternations per hour and featuring a silicon balance spring for improved magnetic resistance. Its power reserve reaches 72 hours. The model has water resistance of 5 bar.
