Holthinrichs LAB Series GMT: 3D-Printed Titanium and Copper Patina Innovation
Holthinrichs LAB Series GMT: 3D-Printed Watchmaking Reaches New Heights
The Dutch brand Holthinrichs has spent a decade pushing the boundaries of 3D printing in watchmaking. According to aBlogtoWatch, the brand's latest LAB Series GMT represents the pinnacle of additive manufacturing technology, combining hand-patinated copper dials with intricately carved titanium cases. At €6,500 EUR, this limited edition of 100 pieces showcases what's possible when traditional craftsmanship meets cutting-edge manufacturing.
The Art of 3D-Printed Cases
Holthinrichs has mastered the art of additive manufacturing to create cases that would be impossible with traditional machining. The 38.5mm titanium case features sweeping lugs with "the thinnest possible lug structures" that have been hollowed and carved to create ribbon-like slits following the lugs' wavelike form.
The finishing process is equally impressive. Certain surfaces are left raw to showcase the 3D printing process, while others receive brushing, polishing, or sandblasting. This combination of textures creates a watch that is both technically advanced and visually striking.
Hand-Patinated Copper Dials
Each dial is individually created using copper that develops a natural patina. The GMT model features a top-down depiction of the globe in relief against the dial, achieved through selective carving and hand-brushing. The brass crescent GMT hand adds warmth to the verdigris tones of the dial.
