Holthinrichs LAB Series: Celebrating a Decade of 3D-Printed Horology with 1.S and GMT Models

Holthinrichs, a Dutch brand celebrated for its pioneering approach to watchmaking, is marking a decade of innovation with the introduction of its latest creations: the LAB Series 1.S and GMT timepieces. The company's core identity revolves around additive manufacturing, more commonly known as 3D printing, a method few have truly mastered in the intricate world of horology. This commitment to experimental production techniques defines every aspect of Holthinrichs' offerings, making each collection a testament to pushing conventional boundaries. The new LAB Series serves as a prime example of this philosophy, allowing the brand to explore novel designs and functionalities.

These new additions to the LAB Series are not merely watches; they are a culmination of ten years of dedicated research and development in 3D printing. They showcase Holthinrichs' progress in crafting complex titanium cases with diverse finishes, creating unique copper patina dials by hand, and integrating reliable Swiss automatic movements. While the brand's 'Signature Ornament' series offers a more traditional entry point, the LAB Series is where the true artistic and technical experimentation unfolds, featuring elaborate hand-patinated dials, advanced functions, and unprecedented demonstrations of 3D-printed case intricacies. This collection stands as a bold statement of what is achievable when traditional watchmaking is fused with cutting-edge manufacturing.

The Intricate Craftsmanship of 3D-Printed Cases

The defining characteristic of any Holthinrichs timepiece, and particularly pronounced in the LAB Series, is its meticulously crafted 3D-printed case. Michiel Holthinrichs, the brand's founder, has continuously refined this innovative manufacturing technique over the past decade, pushing the limits of what is possible in watch design. Earlier models, while impressive, served as precursors to the refined and sophisticated cases seen today. The evolution is evident in the current 38.5mm titanium cases, which boast a graceful, sweeping silhouette reminiscent of the Signature series, but elevated with extraordinary lugs. These lugs, described by the brand as "the thinnest possible," are not only hollowed but intricately sculpted with wavelike forms and ribbony slits, showcasing a remarkable blend of strength and delicate artistry.

Further enhancing the distinctiveness of these cases is the thoughtful application of various finishes. Certain sections of the case are minimally treated, deliberately exposing the raw, textured essence of the 3D printing process, highlighting the material's inherent beauty. In contrast, other areas, such as specific facets of the concave bezel, are meticulously brushed and polished, creating a dynamic interplay of light and shadow. The central concavity of the case presents yet another tactile experience with its smooth, satin-like finish. A domed sapphire crystal elegantly tops the structure, complemented by a discreet crown that, despite its small size, contributes to the watch's overall refined aesthetic. This blend of raw texture and polished sophistication underscores the brand's commitment to both innovative manufacturing and exquisite detailing.

Distinctive Dials and Advanced Movements

The new Holthinrichs LAB Series models feature striking in-house copper patina dials, a signature element of the brand's artistic expression. Each dial possesses a subtle curvature, enhanced by a titanium flange that hosts the hour markers and a matching handset, both equipped with Super-LumiNova for excellent legibility. The contrast between the silver hands and the verdigris dial ensures readability under various conditions. The finishing and unique patina of every dial are meticulously applied by hand, reflecting the artisanal dedication inherent in Holthinrichs' creations. However, beyond these shared characteristics, the 1.S and GMT dials diverge significantly in their design and functionality, offering distinct visual and operational experiences.

The Holthinrichs LAB Series 1.S dial evokes imagery of lunar impact craters, with its rough, radiating texture emanating from an off-center small seconds subdial. This subdial, a recessed area with a subtle ridge, takes center stage, its prominence amplified by a deliberate scraping away of the patina to reveal a brownish undertone. A gold Holthinrichs signature at 12 o'clock provides visual balance. Conversely, the LAB Series GMT presents a more elaborate scene with an azimuthal depiction of the globe in relief, achieved through selective carving and brushing. While the brass crescent GMT hand adds a touch of elegance, the GMT scale's hour markers are subtle, blending with the dial and posing a slight challenge for quick reading. Both models are powered by Swiss automatic Sellita movements visible through sapphire casebacks. The GMT uses the SW330-2 "caller" movement, while the 1.S employs the less common, yet efficient, SW360 for its small seconds function. Each movement features custom, hand-patinated, carved, and heated rotors crafted in-house by Holthinrichs, underscoring the brand's dedication to integrated design and meticulous craftsmanship.
