GS Factory presents the Longines Master Collection Moonphase 42mm new dial edition, where countless refined details come together on a single dial, offering an elegant and highly balanced visual experience.
The watch is developed using three original timepieces for mold creation, ensuring refined craftsmanship and close wrist-worn authenticity.
The case is available in 42mm, with a 40mm option also offered. It is crafted from high-quality 316L stainless steel with fine polishing and brushing, delivering a bright and refined metallic sheen with smooth, elegant lines. The integrated straight lugs are formed as one piece with the case, ensuring a comfortable and natural wrist fit.
It is powered by a modified Dandong 7751 movement based on the L687 architecture, with all functions synchronized to the original configuration. This movement is recognized as one of the more refined domestic chronograph base movements, representing a key technical highlight for this model.
The dial features the highly detailed “barley grain” texture with excellent moonphase reproduction. The raised black Arabic numerals are carefully printed with strict reference to the original design, achieving a level of detail close to interchangeable standards.
The watch is equipped with eight heat-tempered blued steel hands, delivering deep color tones and striking reflections under light. The blued steel finishing reflects high-level craftsmanship, creating a vivid contrast between shadow and shine.
Functionally, the watch integrates moonphase, full calendar, 24-hour display, and chronograph features in a coherent layout. The L687-style automatic movement operates at 28,800 vibrations per hour with a power reserve of approximately 45 hours, ensuring stable and practical performance.
GS Factory focuses on producing widely recognized high-quality Longines-style timepieces, continuously improving craftsmanship and detail accuracy. Each model is developed based on original samples to enhance overall realism in both appearance and feel, aiming to deliver strong value and refined finishing for enthusiasts.
