Holzkern Openhorizon Men's Chronograph • Miyota Quartz Movement • Genuine Blue Marble

The Holzkern Openhorizon is a striking men's chronograph that combines authentic pilot watch aesthetics with a unique blue marble dial. The high-quality stainless steel case in silver measures 44 mm in diameter and 13 mm in height — a bold presence on the wrist, yet comfortable to wear. The centrepiece of the watch is its dial crafted from genuine blue marble: thanks to its natural veining, every single piece is a one-of-a-kind creation that unites cutting-edge watchmaking with the treasures of nature.

The Openhorizon is powered by a precise Japanese Miyota quartz movement with an integrated chronograph function. The coated stainless steel bezel features a tachymeter scale, a hallmark of classic pilot watches. The hardened mineral glass reliably protects the distinctive blue marble dial against scratches. The 5-link stainless steel bracelet in silver is secured by a comfortable safety folding clasp and can be individually adjusted using the included extra links and tool. The watch is water-resistant to 5 bar and weighs 152 g.
