The Circularis Automatic features the MSA01, the first automatic caliber specially developed for MeisterSinger single-hand watches.
It ensures that the large hour hand moves with consistent smoothness. The twin in-line mainspring barrels collect the energy required for the 120-hour power reserve and make sure the watch always keeps time with excellent precision. The power is generated by a central rotor that features crescent-shaped apertures, making it possible to view the specially designed movement at any time. Here, too, fine ornamental cuts and a unique bridge underline the aesthetic sophistication of this MeisterSinger watch. With the purely functional typography of the applied hour digits and the typical minute scale, the Circularis Automatic also follows the MeisterSinger design principles.
The convenience of automatic winding is reflected in the Superluminova markings of the indices, which make it possible to tell the time, even in the dark. Unlike the hand-wound version, the Circularis Automatic displays the date in a circular aperture positioned at 6 o’clock. Its stainless steel case is 43 millimeters in diameter and fitted with a domed sapphire glass over the dial as well as a sapphire glass exhibition back, securely fastened with four screws, that provides an excellent view of the movement. The Circularis comes with a double-folding clasp.
