This timepiece is in pristine condition with no apparent signs of wear. It comes as a complete set including both inner and outer boxes and warranty papers dated December 2025. MSRP: 23,900 USD.
The Masterlink is the first integrated-bracelet timepiece from the Geneva-based Maison — a 38mm × 38mm asymmetric polygon in medical-grade 316L stainless steel measuring 7.99mm in thickness, designed to push the boundaries of in-house movement engineering and industrial design simultaneously. The signature "smile" cutout at 6 o'clock is retained from the Grand Seiko-influenced GC collection DNA, while the upper portion evolves into a squarer geometry — a duality that is mirrored in each bracelet link, which curves at the bottom and follows geometric lines at the top. The double-layered sunburst silver dial features a vertical stripe finishing, applied baton-shaped hour markers with white SuperLumiNova fill, Arabic numerals at 3, 9, and 12 o'clock, and skeletonized baton hands. The hidden-fastener integrated bracelet is developed entirely in-house, with butterfly clasp, hex-plate, and push-button release concealed within the bracelet architecture for a completely seamless profile. A sapphire exhibition caseback reveals the GCA 5401 movement and its offset micro-rotor. Retailing at 23,900 USD, this example is offered meaningfully below current retail. The in-house GCA 5401 is an ultra-thin self-winding movement with offset micro-rotor measuring just 2.67mm in profile, comprising 176 components and 29 jewels, beating at 21,600 vph (3 Hz), and delivering approximately 50 hours of power reserve, water-resistant to 100 meters.
Delivery is via fully insured FedEx Priority Overnight to your nearest FedEx Ship Center within the continental U.S. All photos and videos are captured using professional macro equipment to accurately disclose condition; minor blemishes shown, as well as occasional fingerprints visible due to handling during photography, may not be apparent under normal lighting or wear.
