Holthinrichs celebrates ten years with a sculptural copper-patina small seconds

Dutch independent Holthinrichs marks its tenth anniversary with the SIGNATURE LAB 1.S, a watch that makes manufacturing texture part of its visual identity. A hand-treated copper dial develops a striking blue-green oxidised surface, with engraved radial lines converging on a small-seconds register at six. No two patina surfaces are expected to appear precisely alike.

The 38.5 mm Grade 5 titanium case is produced using additive manufacturing, allowing sculptural, skeletonised lugs and flowing transitions that would be difficult to make in a conventional case. Deliberate contrasts between raw printed areas and hand-finished surfaces give this Delft-made design a distinctly architectural personality.

An automatic Sellita SW360 powers the hours, minutes and small-seconds indication. The leather strap's warm colour complements the oxidised dial. These specifications are from contemporaneous manufacturer and specialist coverage, not from independent testing by ChronoLume.
