COUNTERFEIT LONGINES CONQUEST CHRONOGRAPH (REF. L3.662.4 MARKING): IDENTIFICATION

A wristwatch bearing Longines Conquest branding and the reference number L3.662.4. While styled as a modern sports chronograph with a blue dial and steel bracelet, horological diagnostics indicate this is a replica. The subdial configuration features a 24-hour indicator at 3 o'clock—a hallmark of inexpensive quartz modules—rather than the proper 30-minute or 12-hour chronograph registers found on genuine Longines calibers. Furthermore, a genuine L3.662.4 utilizes an automatic movement requiring a 12-9-6 subdial layout.

PRODUCTION & REFERENCE HISTORY

The Longines Conquest line was introduced in 1954, representing the brand's first step into named watch families. Modern iterations, like the genuine L3.662.4, are robust sports chronographs originally powered by Swiss Valjoux-based mechanical calibers. The proliferation of the luxury watch market has led to widespread counterfeiting. Replicas often copy the external design language of prestigious models while substituting sophisticated Swiss mechanical calibers with mass-produced quartz modules, resulting in the functional layout discrepancies visible here.

WATCHMAKER'S ASSESSMENT

Vintage Watchmaker & Horology Specialist

Horologist

The presence of a 24-hour subdial on a watch stamped with an automatic Valjoux-based reference number provides definitive proof of a movement mismatch typical of counterfeits.

CONDITION & GRADE

Poor (Non-Authentic)

Grading breakdown

Standard horological grading scales do not apply to counterfeit timepieces. The physical condition shows heavy wear, rounded edges from cosmetic polishing, and generic clasp components.

Condition

The stainless steel case, bezel, and bracelet exhibit extensive surface scratching and wear. The user context notes the watch is 'Restored', which likely refers to a battery replacement, superficial case polishing, or a quartz module swap rather than a true mechanical service, given the non-genuine nature of the components.

YOUR INPUT VS. SCAN

How your provided context compares with Curiosa.com scanner findings.

What Aligned

The user's 'Restored' claim aligns with the visible rounding on the case and bezel edges, suggesting a superficial cosmetic polish was previously performed.

What Conflicted

The user's implication of restoring a valuable timepiece conflicts with the visual evidence of a replica movement layout (3-6-9 with a 24h dial), rendering traditional mechanical restoration impossible.
