Launched in 2014, the Circularis with its 14½-line MSH01 manual wind mechanical movement is the basis for a new generation of single-hand watches superbly crafted by the Münster-based manufacturer. Within three years, the team at MeisterSinger’s long-standing cooperation partner in Switzerland designed from scratch a caliber timepiece that is aesthetically unmistakable, but above all meets the sophisticated standards both companies have come to expect in state-of-the-art watchmaking. The MSH01 is a robust piece – its design is focused on the essentials. An unusually long power reserve, a uniquely designed movement, and its design potential for subsequent watch concepts stood at the forefront of the development.
Twin in-series mainspring barrels provide the movement with an abundant 5 days power reserve. The in-series springs guarantee a smoother power delivery to the mechanism than, for instance, a single spring, providing the movement with a high degree of power precision. In addition to the mainspring barrels, the bridge design gives the movement a highly unusual geometry – and demonstrates the aspiration of the founder of MeisterSinger, Manfred Brassler, to merge design ideals with high technical refinement. For the first time, he not only designed the face and the case of a watch, but also the balanced appearance of the movement. The joy of his attention to detail is also obvious in the finishing – the elaborate circular polishing of the rhodium-plated bridge, mirror-polished bevels, blued screws, and the engraving in gold make the MSH01 a pleasure to behold.
In technical terms too, further details point to the manufacturer’s firm endeavor to remain on its independent path as a maker of single-hand watches. Since a single, long hour hand needs to run with particular precision, a dial train with spring wheel was integrated in the movement in order to minimize the backlash of the hand. The assortment too has been specially developed for this movement design, which means that independence is guaranteed for the design of further products in this line.
The Circularis is fitted with a newly designed extra-large crown for easy winding. It takes a little time until sufficient tension has built up in the rotating barrels and the balance wheel begins to rotate, but that makes winding the watch a micromechanical experience and a pleasant little ritual – even though it is only needed every five days.
With a needle hand, zeros placed before the single digits and line indices on the face, the Circularis is a classic MeisterSinger – but with newly interpreted design trademarks. The hour digits are displayed in a fine serif typeface on the face. A circular recess in the center gives it greater structure, particularly in its interplay with the sunburst pattern on its sapphire-blue or silver-white face. The twelve narrow hour indices in the inner circle of the face underline the nature of the single-hand watch.
The Circularis is available with three different face designs (sunburst silver-white, sunburst sapphire blue, ivory) on a wristband made of genuine alligator leather (cognac and dark brown) with a double-folding clasp.
