Hanhart PIONEER Mk I black

Hanhart: pioneer of precision chronographs

Hanhart set standards early on in the field of highly functional precision chronographs. In 1938, the company developed the famous single-pusher chronograph for naval officers with the specially designed "Caliber 40". Just a year later, another milestone followed: the first pilot chronographs with the innovative "Caliber 41". This column-wheel movement offered a unique flyback function that allowed pilots to reset and instantly restart the chronograph with just the push of a button.

Renaissance of legends in the 1990s

In the 1990s, Hanhart brought his historical masterpieces back to life. The Swiss-German watch brand brought faithful replicas of the legendary chronographs onto the market, building on its long tradition and technical excellence. Hanhart caused a stir in particular in 2012 when the models Pioneer Mk I, Mk II and TachyTele were introduced with elegant, old white dials. These new editions have become classics that delight both collectors and watch lovers.

The one-pusher chronograph: Pioneer Mk I

The Pioneer Mk I is a homage to Hanhart's first precision chronograph from 1938. This extraordinary single-push chronograph is characterized by a special mechanism in which all functions – start, stop and zero setting – are operated using a single push button. Unlike models with two pushers, the chronograph second hand does not continue to run after stopping. The next press resets the pointer immediately to zero. For this special feature, the caliber used had to be slightly modified: The shift lever was adjusted so that the cam on the lowest level received an additional point. This means that the lever controls not just two, but three positions, which makes the one-push function possible.

Robust housing for maximum longevity

The Pioneer Mk I impresses with an extremely robust housing that is designed for longevity and suitability for everyday use. Like its historical predecessors, it is equipped with a closed, screwed case back. This construction guarantees watertightness up to 10 bar (approx. 100 meters) and at the same time offers optimal protection from external influences.

Timeless vintage look with high wearing comfort

The design of the Pioneer Mk I combines historical charm with modern comfort. Your calfskin strap is not only durable, but also comfortable and offers a pleasant feeling on the wrist from the first time you wear it. The typical Hanhart bracelet is complemented by stainless steel rivets, which underline the vintage character of the watch. A high-quality pin buckle ensures a secure fit, whether in the office or at leisure.

Perfect dimensions for everyday life

With a case diameter of 40 mm and a height of 15 mm, the Pioneer Mk I is both elegant and present on the wrist. The minimalist design with the modern Hanhart logo fits perfectly into the existing Pioneer collection. Thanks to its timeless look and proven Hanhart quality, it is the ideal companion for everyday use.

Conclusion: A watch for connoisseurs and collectors

The Pioneer Mk I combines the history of the Hanhart chronographs with the latest in watchmaking. It is not only a functional timepiece, but also a real collector's item that is reminiscent of the beginnings of pilot chronographs. With its combination of historical details, timeless design and technical precision, it makes a strong statement in the world of luxury watches.
