Hanhart PIONEER MonoScope silver, fluted bezel

The Pioneer MonoScope from Hanhart impresses with its unique single-pusher technology, which controls all chronograph functions. This feature is reminiscent of the brand's legendary predecessors, which also used only a single pusher. Particularly striking are the widely spaced displays for the small seconds and the 30-minute counter, a tribute to the historical precision watches of the traditional Swiss-German brand.

At the heart of this watch is an automatic movement, specially adapted to control functions with just one pusher. It ticks within a generous 45-millimeter stainless steel case. In contrast to other models, the lever located at four o'clock remains non-functional. Instead, a large switching lever controls the third strike on the chronograph cam. This is made possible by a modified lower level of the cam, which now has an additional tooth. This allows the switching lever to control three positions, instead of the usual two.

Another technical refinement of this watch is the positioning of the displays for the small seconds and the 30-minute counter on the periphery of the dial. This arrangement is based on the classic Hanhart models of the 1930s, inspired by the 15.5-ligne manufacture caliber used at the time. The symmetry of the dial is emphasized by the arrangement of the displays along a vertical axis to the numerals 2 and 4, as well as 8 and 10. This ensures a harmonious and balanced aesthetic.

Historically, in 1938, Hanhart developed a special single-pusher chronograph for naval officers, utilizing the company's "Calibre 40." Here, start, stop, and reset are executed in a fixed sequence via the same pusher. A key difference from models with two pushers is that the chronograph seconds hand cannot be restarted after being stopped; instead, it immediately springs back to the zero position on the next push.

To ensure the robustness and water resistance of the Pioneer MonoScope, it features a screw-down case back with three indentations for the case key. This is complemented by a riveted strap made of durable calfskin, which feels comfortable from the start. A high-quality pin buckle ensures a secure fit on the wrist. For additional options, Bund straps in various shades of brown and a stainless steel bracelet are also available.

Another striking detail of the Pioneer collection is the red reset pusher. This special feature is based on a charming legend: One day, a young pilot discovered that his wife had painted the pusher with red nail polish so that he would always think of her and return safely. Since 1939, this red pusher has become an unmistakable trademark of Hanhart. It helped pilots prevent accidental resetting of the stopped time during flight, thus staying on course.

The Pioneer MonoScope thus combines historical elements and innovative technology in a shapely, timeless watch. This combination makes it an ideal choice for lovers of classic chronographs with modern demands.
