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.

Questions about this item
What comes in the box with the HydroConquest L3.781.3.98.9 and do I need to buy a strap or tool separately?
The watch ships on a blue rubber strap with a double safety folding clasp and push-piece opener already fitted; no extra strap or sizing tool is required.
Should I choose the stainless-steel-and-rose-gold-PVD version or a different finish for the 41 mm HydroConquest?
This reference is the sole 41 mm model combining a stainless-steel case, rose gold PVD bezel and crown, and blue ceramic bezel insert; other finishes carry different part numbers.
What does the 72-hour power reserve mean for daily wear of the caliber L888?
The movement stores enough energy to keep running for three full days off the wrist, so the watch will still be ticking after a weekend without winding.
