Precision Timekeeping

The Longines Record L2.820.4.57.6 is a 38.5 mm stainless steel watch powered by the Swiss automatic chronometer caliber L888.4. It beats at 25,200 vibrations per hour and delivers up to 64 hours of power reserve. A scratch-resistant sapphire crystal protects the lacquered black dial set with 13 white diamonds. Water resistance is rated to 30 meters.

Wrist Presence

This model suits buyers who want a certified chronometer with diamond hour markers and a transparent caseback revealing the movement. The 10.70 mm case thickness and 19 mm band width create a substantial profile on the wrist. Buyers who need deeper water resistance or a larger case diameter should look at something else.

Daily Integration

The stainless steel bracelet fastens with a triple safety folding clasp and push-piece mechanism for secure wear. A bordered date window sits at 3 o'clock beside the signed crown. The fixed bezel and 100 feet water rating support everyday use, while the exhibition caseback allows visual confirmation of the movement finishing.

Questions about this item

Does the 38.5 mm stainless steel case fit a standard 19 mm band without extra links?

The bracelet is integrated at 19 mm width and secured by a triple safety folding clasp, so no additional links are required for the supplied strap.

Will the sapphire crystal and 30 m water resistance hold up if I keep wearing my older leather-strap watch in light rain?

Sapphire crystal resists scratches and 30 m rating covers splashes and rain, though neither watch is suited for swimming or showering.

How can I confirm the L888.4 movement is keeping COSC accuracy after I set the date at 3 o'clock?

Observe daily rate over several days; COSC certification allows -4/+6 seconds per day, and the 64-hour power reserve lets it run through a weekend without winding.
