HydroConquest 300M Diver

The Longines HydroConquest L37814769 is an automatic diver's watch built for 300 metres water resistance. A stainless steel case holds a sunray grey dial with dotted markers and numerals at 12, 6 and 9 o'clock. The L888 calibre with 21 jewels drives the analog display and date window. A grey rubber strap with a buckle clasp completes the sports-luxury design.

Suited to daily wear and recreational diving

Buyers who want a robust automatic watch with high water resistance and a rubber strap for active use will fit this model. Those who prefer a metal bracelet, a ceramic bezel insert or a thinner profile for formal cuffs should look at something else. The 21 mm band width and buckle clasp are fixed specifications that may not suit every wrist preference.

300 metre water resistance decides fit

The single specification that determines whether this is the right part is the 300 metre depth rating. If your activities require that level of certified resistance, the watch meets the requirement. If your needs stop at splash resistance or you require a higher professional saturation rating, this is not the correct choice.

Questions about this item

How much power does the automatic L888 caliber with 21 jewels need when worn all day?

The automatic L888 movement winds itself from wrist motion, so it requires no battery or external power source during daily wear.

What wrist size suits the 21 mm rubber strap and buckle clasp?

The 21 mm rubber strap fastens with a buckle clasp and fits most adult male wrists; the supplied length covers typical sizes without extra links.

Will the 300 m water resistance hold up if I keep wearing my older mechanical dive watches?

Yes, the 300 m rating and screw-down crown on this model are independent of any other watch you own and remain effective for diving.
