Authentication

COSC certification text must appear on the dial; non-COSC Record variants exist and are a different reference.

Known issues in the market
  • Dial does not show COSC certification text; the watch is a non-COSC Record variant being misrepresented as chronometer-certified.
  • Papers do not include COSC certificate; the chronometer certification is a key part of the Record's value proposition.
  • Rate has degraded from COSC standard on a used example; verify with a timing machine if chronometer accuracy is being represented.
AreaWhat to checkWhat is correctRed flag
dialCOSC chronometer text"Chronometer" or "COSC" text appears on the dial below the brand name; text is crisp and matches the font used in Longines Record documentationMissing chronometer text on a watch sold as COSC certified; text that appears different from the Longines Record specification
casebackCal. L592.2 identificationCaseback shows L592.2 caliber designation; Longines finishing visible through exhibition casebackDifferent caliber number than L592.2; non-Longines finishing on the movement
movementTiming rate verificationMovement runs within COSC standard (-4/+6 seconds per day) when measured on a timing machineMovement running outside COSC standard on a watch being sold as a COSC chronometer; any claim of certified accuracy without timing machine verification
Common legitimate replacements
  • Papers confirming COSC certification are a required component of the Record's value; missing papers reduce desirability significantly.
  • The thin dress case is vulnerable to dents at the lugs; inspect lug joints carefully on any used example.

Authentication guide

Last reviewed June 2026

The Record is Longines' COSC chronometer line with silicon components. The caseback carries the COSC certificate number; that engraving is the first authentication check.

Known reproduction risks

toggle
LOW

The Record is a quiet collector's piece without reproduction activity. The COSC certificate number on the caseback is the simplest first check.

  • Missing COSC number on caseback
  • Case thicker than 8.1mm (wrong case)
  • Non-exhibition caseback showing non-L592 movement through a opened back

Caseback COSC Engraving

Original: COSC chronometer certificate number engraved on the solid caseback

Replacement tells
  • Missing COSC certificate number on a watch sold as COSC-certified
  • Caseback from a non-Record Longines (different profile or text)
Dial

Original: Clean dress dial with applied indices; very slim profile consistent with 8.1mm total height

Replacement tells
  • Thicker-than-expected case suggests caseback swap or wrong case
  • Applied indices replaced with printed after service

Case back markings

toggle
2018 to present
  • Solid screwback with COSC certificate number engraved
  • Engraved: LONGINES, reference L2.821.4.92.4, 30M water resistance
  • Cal. L592.2 inscription on caseback or on movement (if exhibition)

Movement tells

toggle
  • The L592.2 is COSC-certified; it should perform within -4/+6 seconds per day. A watch running significantly outside this on a recently serviced example warrants timing machine verification.
  • The 54-hour power reserve is confirmed by fully winding and timing the rundown; a watch consistently running under 48 hours needs mainspring attention.
  • Silicon components in the L592.2 provide magnetic resistance; a magnet test should show no significant rate deviation.
  • The slim 8.1mm case height is achieved with careful movement height management; any thicker-than-expected profile suggests a caseback or movement issue.
  • Hacking seconds should engage cleanly; the Record is a dress watch and should be serviced to dress-watch standards of cleanliness and precision.
