5C Factory proudly presents a refined aesthetic masterpiece from the Jaeger-LeCoultre Master Series — model 1558420, a high-end version featuring a true small seconds display at 6 o’clock.
Key Details
Case Design
Case size: 39mm × 12mm. The watch features a slightly domed “box-style” crystal, carefully refined through repeated adjustments to achieve a curvature closely matching the original design. This preserves the authentic horological character while maintaining a distinctive visual identity.
Dial Layout & Functions
12 o’clock: dual apertures displaying weekday and month
6 o’clock: sub-dial for small seconds with moonphase indication
Perimeter: date hand display
All functions are designed to replicate the original layout with strong emphasis on symmetry, depth, and mechanical layering.
Clasp Engineering
The folding clasp adopts a seamless structure with no visible gaps from the side profile. Its curvature is consistent with the original specification, ensuring improved wrist comfort and a more integrated visual flow.
Movement
Powered by a 5C Factory customized modified Jaeger-LeCoultre-style 866/1 automatic movement, engineered for stable performance and reliable timekeeping.
A timepiece defined by restrained elegance on the surface and mechanical complexity within—highlighting the brand’s signature aesthetic balance.
