Hercules, historically Henzi & Pfaff, is a Swiss independent watch brand that specializes in a concept it defines as Luxury Alpinism. While the brand is currently headquartered in the Swiss Jura mountains, its roots trace back to 1946 in Pforzheim, Germany, where it was originally founded by Robert Henzi and Robert Pfaff. The brand gained international prominence in 1953 when mountaineer Hermann Buhl wore a Hercules timepiece during the first successful solo ascent of Nanga Parbat. After becoming dormant during the quartz crisis of the 1970s, Hercules was revived in 2022 by Adriaan Trampe, a Swiss watchmaker of Dutch origin and the former owner of EZA Watches.
Enthusiasts are drawn to Hercules for its blend of historical mountaineering heritage and high-specification modern watchmaking. The brand is noted for its technical transparency and rigorous quality standards, with its timepieces undergoing “Observatoire Chronométrique+” certification by Timelab in Switzerland. Design details that resonate with collectors include the use of rare materials like tantalum and unique horological finishes, such as topographic maps of the Nanga Parbat mountains engraved on the movement and filled with Super-LumiNova. This focus on artisanal, low-volume production positions the brand as a specialized choice for those interested in tool watches with a luxury execution.
The brand’s catalog is centered on its “Luxury Alpinism” series, with the HP1 and HP2 serving as the primary models. These watches typically feature 40mm cases and are available in stainless steel or tantalum. The HP series is distinguished by its dial variations, including the “Snow Dial” collection which offers colors such as Ice Blue, Ice Pink, and Snow White. Technically, these pieces are powered by sophisticated movements, including a bespoke micro-rotor automatic caliber and a hand-wound double-barrel movement that provides a 120-hour power reserve. These movements are often visible through sapphire casebacks, showcasing the brand’s signature mountaineering-inspired engravings.
