Specht & Söhne SP2652A3 KALIBER IMPERIAL Automatic White Jump Hours

Kaliber is a study in mechanical clarity. Designed for those who appreciate engineering over excess, it blends modern minimalism with traditional horology in a way that feels both purposeful and timeless.

At its heart is the Seagull ST1721 jump-hour mechanical movement—a complication that replaces the conventional hour hand with a precisely advancing hour window. The result is a dial that feels architectural and deliberate, rewarding the wearer with a quiet mechanical ritual at the top of every hour.

The 39 mm case is crafted from 316L stainless steel, striking an ideal balance between presence and wearability. With a slim 10.4 mm profile and a compact 46.8 mm lug-to-lug, Kaliber sits comfortably on the wrist while maintaining a refined, contemporary stance. A screw-down crown and closed steel caseback reinforce its solid, tool-grade construction.

An AR-coated sapphire crystal protects the dial, ensuring excellent legibility while minimizing reflections. The layered dial design—with its recessed textures and clean typography—adds depth without distraction, allowing the jump-hour display to remain the focal point.

Finished on a textured leather strap, Kaliber is not a watch that shouts. It’s a watch that speaks quietly to those who understand mechanical intent, precision design, and understated confidence.

Kaliber by Specht and Söhne — engineered time, expressed with restraint.
