Albishorn Thundergraph Albishorn continues its journey through the annals of horology with the Thundergraph, a chronograph designed as if it were the ultimate tool watch for the Swiss 1952 Mount Everest expedition. This “Imaginary Vintage®” timepiece fills a hypothetical gap in history, blending mid-century design with modern craftsmanship. The concept? A rugged yet elegant alpine chronograph, built to withstand extreme cold, altitude, and the unforgiving elements of the Himalayas.
The Thundergraph’s dial is a masterclass in readability and vintage-inspired design. Featuring the “California ghost” dial, it maintains the iconic split layout but omits Arabic numerals in favor of two strategically placed subdials. Luminescent hands, oversized Roman numerals, and triangular indexes ensure visibility in low-light conditions, while the oversized conical bezel—designed for easy grip with gloves—adds both form and function. The crown at 10:30 and monopusher at 9:30 reflect thoughtful ergonomics, allowing for seamless operation even in harsh conditions.
Under the hood, the Thundergraph houses a proprietary hand-wound chronograph movement, developed in La Chaux-de-Fonds and certified by COSC for superior accuracy. With an ultra-thin 5.70 mm movement height and an impressive 65-hour power reserve, it recalls the golden age of Swiss chronographs while delivering modern precision. The stainless steel case, optional bronze crown, and engraved case back (featuring a Swiss cross and rope motif) reinforce its alpinist heritage.
From its historically inspired roots to its tool-watch practicality, the Albishorn Thundergraph is a tribute to mountaineering history. The chronograph that might have been—but thanks to Albishorn, now is.

Albishorn Type 10 Sihlwald In October 2024, Albishorn introduced its second chronograph, the Type 10, as a fictional predecessor to the renowned Type 20. Albishorn specializes in “Imaginary Vintage®” watches—timepieces that blend seamlessly into watchmaking history but are imagined creations. The Type 10 answers the hypothetical question of what a predecessor to the Type 20, designed in 1948, might have looked like.
The Type 10 is a monopusher military chronograph with a patented proprietary movement designed to meet the needs of 1940s pilots. It includes a patented additional complication: a chronograph operating indicator at 12 o’clock. This small dot changes color depending on the chronograph’s state—black for reset, red for running, and white for stopped—allowing pilots to easily check its status. The watch also features a unique dial layout with two sub-dials at 4:30 and 7:30, luminous markers for enhanced readability in low light, and a sleek 12mm stainless steel case with a black DLC-coated rotating bezel.
The Type 10 is available in two versions: the Type 10 Classic, embodying the purest form, and the Type 10 Sihlwald, which adds a green fumé dial, red chronograph hands, and a bronze crown.
