Hanhart was a pioneer in the field of reliable, highly functional precision chronographs. In 1938, the company designed the single-pusher with its own ‘Calibre 40’ for naval officers. Just one year later, the first pilot's chronographs followed with the ‘Calibre 41’ - a switch-wheel movement with flyback function. When the Swiss-German watch brand reissued faithful replicas of these legendary chronographs in the 1990s, it built on its long tradition and high level of expertise. In 2012, Hanhart presented the Pioneer Mk I, Mk II and TachyTele models with elegant antique white dials.
SINGLE-BUTTON CHRONOGRAPH
SPECIAL FUNCTION
The Pioneer Mk I is a replica of the first precision chronograph made by Hanhart in 1938. With this unusual single pusher, all chronograph functions - start, stop and zero setting - are performed by a single pusher and always run in strict sequence. Unlike its two-pusher counterpart, the chronograph second hand cannot be kept running after it has been stopped; the next time it is pressed, it inevitably jumps back to its starting point. For this reason, the caliber used for the Mk I had to be slightly redesigned. The lever, which is located directly below the pusher that is normally positioned at 4 o'clock, has no function. The third stroke on the chronograph cam is thus performed by the large gearshift. For this purpose, this cam is modified at Hanhart so that an additional prong runs along its lowest level. This allows the gearshift to control not two, but three positions.
WATERPROOF UP TO 10 BAR
ROBUST CASING
To ensure the best water resistance and robustness, it is equipped with a closed, screwed case back like its predecessors, which guarantees the watch a water resistance of up to 10 bar
VINTAGE CHARACTER
THE PERFECT EVERYDAY COMPANION
The PIONEER Mk I measures 40 mm in diameter and 15 mm in height. The typical Hanhart leather strap with stainless steel rivets emphasizes the vintage character of this watch and ensures a pleasant feel on the wrist. It is the perfect everyday companion, whether for work or leisure. The historical character has been combined with the modern Hanhart logo to perfectly complement the PIONEER collection.
