Longines HydroConquest L3.781.3.98.9 41 mm blue dial rubber strap watch

HydroConquest 41 mm dive watch

The Longines HydroConquest L3.781.3.98.9 is a 41 mm stainless steel dive watch with a rose gold PVD bezel and a blue rubber strap. It suits buyers who want a Swiss automatic timepiece rated for 300 m water resistance and a 72-hour power reserve.

Check wrist size and clasp preference

The band width is 21 mm and the case thickness is 11.90 mm, so verify that the proportions suit your wrist. The double safety folding clasp with push-piece opening requires a secure fit; ensure you are comfortable with this fastening style before ordering.

Build around a single versatile watch

The screw-down crown and uni-directional rotating bezel support dive timing, while the sapphire crystal and solid caseback protect the L888 calibre beating at 25,200 vibrations per hour. The blue dial with Arabic markers at 6, 9 and 12 and a date window at 3 o'clock covers daily wear without needing additional straps.
