Longines Record Automatic COSC 38.5 mm Black Dial Diamonds L2.820.4.57.6 watch

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.
