Holthinrichs Joins Forces With The Horology Club For The “Concrete Jungle”
Holthinrichs has unveiled a new addition to its Signature Series, the Ornament Concrete Jungle, created in collaboration with The Horology Club (THC). This exclusive timepiece draws inspiration from the vibrant urban skyline of Hong Kong, THC’s hometown, and features innovative design elements that set it apart in the world of haute horology.
Crafted with precision, the Ornament Concrete Jungle offers two case options. The CNC-machined Signature Ornament and the Signature LAB with 3D-printed skeletonized lugs showcase Holthinrichs’ mastery of titanium. Both variations feature a Grade 5 titanium base with a 38.50mm diameter, a thickness of 9.85mm, and a 46mm length. Protected by sapphire crystal on both sides, the watch includes a smooth bezel, a crown adorned with the brand’s logo at 3 o’clock, and 50 meters of water resistance.
The standout feature of this watch is its matte gray-toned concrete dial, made using a LumiNova blend that emits a light blue glow in the dark. This luminous surface incorporates intricate oracle bone script numerals—a highly challenging Chinese script—around the edges. Complementing the dial are openworked center hands and the brand’s signature at noon, creating a design that resonates with urban sophistication.
Inside, the Ornament Concrete Jungle houses the reliable Sellita SW300 automatic movement, a 25-jewel mechanism operating at 28,800 vibrations per hour. This movement provides a power reserve of up to 50 hours and is enhanced with an 18k rose gold-plated turbine-shaped rotor, underscoring the watch’s luxurious appeal.
The timepiece is paired with a gray Nubuck leather strap, accompanied by an additional Delugs rubber sailcloth strap. The CNC-machined version is available for a limited two-week order period at a price of €3,850, while the 3D-printed version, limited to just 50 units, is priced at €5,600.
With its innovative materials, artistic craftsmanship, and homage to Hong Kong’s dynamic skyline, the Holthinrichs Ornament Concrete Jungle is a true collector’s piece for watch enthusiasts and urban aesthetes alike.
