This highly complex multi-function timepiece is inspired by the traditional craftsmanship and mechanical sophistication of Longines Master series, emphasizing full calendar chronograph functionality and detailed mechanical architecture.
The watch features a 40mm stainless steel “hammer-pressed” case made from 316L steel, refined through CNC precision engraving to ensure structural accuracy, durability, and 100-meter water resistance performance.
It is powered by a 7751-based modified automatic mechanical movement with upgraded components, blue steel wheel finishing, and enhanced stability, offering an approximate 48-hour power reserve.
The dial uses blued steel heat-treated hands combined with a gold-tone moonphase display, and incorporates a complex multi-register layout that visually balances chronograph, calendar, and moonphase functions with high readability.
A sapphire crystal glass protects the dial, while detailed craftsmanship such as engraved textures and layered dial depth enhances the overall visual refinement.
The bracelet is constructed from segmented 316L stainless steel, hand-polished and assembled for a smooth, scratch-free wearing experience, with an additional leather strap and buckle set included for versatility.
Overall, this model highlights high-complexity mechanical design, moonphase chronograph integration, refined dial architecture, and the signature elegance of the Longines Master series.
