![]() The centers of rotation of the two small hands form a vertical line with the numerals 2/4 and 8/10 so that the display corresponds exactly with the 1930s’ design with the Caliber 40. Shifting them outward almost to the edge of the dial also required a modification. The distinctive red pusher has been a Hanhart trademark since 1939 and is designed to prevent the unintentional stopping of the chronograph.Īnother unique feature of the Pioneer MonoScope is the placement of the subdials for the small seconds at 9 o’clock and for the 30-minute counter at 3 o’clock. For this, Hanhart integrates its own in-house development: a transfer lever to relay power over the additional millimeters of the large 45-mm stainless-steel case. The uncommon position of the single chronograph pusher is a specialty of the house. It has an additional notch so the main operating lever can control three positions.īut that’s not all. The reset is activated using the main operating lever and a modified cam. The lever, which normally sits under the reset pusher at 4 o’clock, has no function. The resurgence of the single pusher is also the characteristic feature of the modern Pioneer MonoScope, currently with a movement based on the ETA Valjoux 7750. In 1938, the company built a monopusher chronograph for marine officers with its own Caliber 40 movement. In the first half of the last century, Hanhart carried out groundbreaking work in the development of functional stopwatches. ![]() Hanhart, Longines and Montblanc are following this ongoing trend and find inspiration in their own history books. This type of display has been around since the early 20th century and is currently seeing a rebound in popularity. The return of the monopusher chronograph follows the same trend of linearity and clarity as the bicompax display, giving us a better overview of the chronograph dial.īicompax is the designation for a dial with only two subdials – one register for the small seconds, usually at the 9 o’clock position, and one for the timed minutes, usually at 3 o’clock. Each of these stopwatches continues to write its own personal history. Previously only a single linear measurement was possible with a single push-button – to start, stop, reset – just like our three current test watches from Hanhart, Longines and Montblanc. ![]() By the mid-1930s, developments from Breitling first resulted in a second chronograph pusher that made it possible to stop and restart the recording of time intervals multiple times. Monopusher chronographs with bicompax displays are reaching deep into the past in two ways.
