FREE Bracelet Adjustment/Sizing
We can adjust the watch bracelet, when you inform us of the required wrist size, in the checkout.
Built for underwater performance without sacrificing Longines refinement, the HydroConquest L3.788.4.70.6 features a commanding 42mm stainless steel case and matching bracelet. Its polished black lacquered dial combines applied hour markers with hands and detailing treated with Swiss Super-LumiNova for enhanced visibility in low-light conditions, while a date display adds everyday practicality. A black ceramic unidirectional rotating bezel allows elapsed dive time to be monitored, and scratch-resistant sapphire crystal with anti-reflective coating on both sides provides lasting clarity. The bracelet is secured by a double-safety folding clasp with a push-piece opening mechanism and integrated diving extension.
Inside, a 21-jewel Swiss automatic mechanical movement with a monocrystalline silicon balance spring beats at 25,200 vibrations per hour and delivers up to 72 hours of power reserve. Its serious aquatic credentials include a screw-in crown, screwed case back, and water resistance to 300 metres. Measuring 11.7mm thick with a 21mm lug width, the watch weighs 168g, giving it the reassuringly substantial feel expected from a capable dive watch.
• Powered by the Swiss made Caliber L888.5 automatic movement with 21 jewels and a power reserve of up to 72 hours
• Presented on a silver stainless steel bracelet with fold over clasp
• Scratch-resistant sapphire crystal, with several layers of anti-reflective coating on both sides
• 42.0mm case width & 51.2mm case length measuring from lug to lug
• 300 metre water resistance
