Verify the reference before anything else
Buy the reference, not the story. Before you spend money on any Jaeger-LeCoultre 344648, confirm that the reference number, case metal, dial variant, and movement all belong together in the manufacturer's own records. Photographs and seller claims are the weakest evidence you can use. The strongest evidence is a hands-on inspection by a watchmaker who can open the caseback, read the movement markings, and measure the case against published specifications. If a seller refuses that step, or demands a deposit before inspection, treat the watch as unverified and move on.
What to look for on a 344648
Case and caseback
Genuine JLC cases carry crisp, deep engraving. Reference numbers, serial numbers, and metal hallmarks sit in straight lines with even spacing. Counterfeits often show shallow laser etching, uneven letter spacing, or a reference number that does not match the case shape. Check the lugs for the correct profile, the bezel for even polishing, and the crown for the right logo depth and thread feel.

Dial, hands, and crystal
Look at the dial under a loupe and in raking light. Genuine printing is flat, opaque, and sharp at the edges. Copies show fuzzy borders, slight bleeding, or raised glossy ink. Applied indices should sit level and reflect light evenly. Hands should be the correct length and finish for the reference, with polished bevels that catch light on one edge. Sapphire should show no distortion at the edges and should not rattle or flex.
Movement and finishing
Open the caseback. Genuine Jaeger-LeCoultre movements show Geneva stripes, circular graining, blued screws, and jewel settings that sit flush. Engraved caliber numbers are cut, not stamped. Rotor engraving is sharp and deep. Copy movements often use plated brass plates, painted stripes instead of brushed finishes, and a rotor with visible play.

Papers and provenance
Match the serial on the caseback to the warranty card, the box label, and any service records. Misaligned fonts between documents are a red flag. Ask for the original purchase date and dealer name, then check that the dealer existed.
Parameter bands to check
- Case diameter: within 0.3 mm of the published spec for the reference.
- Case thickness: within 0.5 mm, measured with calipers at the center of the caseback.
- Lug width: matches the strap or bracelet end link with no gap wider than 0.2 mm.
- Weight: a stainless steel case in this class usually falls between 70 g and 110 g on a leather strap; a large deviation points to a different alloy or a hollow case.
- Power reserve: 40 to 70 hours depending on caliber; test it rather than trusting a claim.
- Water resistance: stated on the caseback and consistent with gasket condition seen during service.
Pitfalls to avoid
- Buying from photos only. Lighting hides dial printing problems.
- Trusting a box and papers as proof. Documents are copied often.
- Ignoring service history. A movement that has never been serviced may need a costly overhaul.
- Accepting a limited edition claim without a matching certificate.
- Paying a premium for a reference number that has been re-engraved onto a different case.
FAQ
Is the 344648 commonly counterfeited?
Popular references attract copies, and any JLC reference sold widely on the secondary market will appear in replica form. Rarity of the reference is not protection.
Can a jeweler authenticate it?
Only if they can open the case and read the movement. A visual check across a counter proves little. Ask for a written inspection summary.
What matters most in the decision?
Movement and case integrity first, then dial originality, then accessories. Papers raise value but never replace a mechanical inspection.
