MeisterSinger Circularis Automatic Old Radium

MeisterSinger expands it premium collection Circularis by presenting the new Circularis Automatic watch with an “Old Radium” look.

The movements for all Circularis models were developed in Switzerland according to exact specifications set out by Meister-Singer in order to ideally meet the special requirements of single hand watches and to ensure an incredibly large power reserve at the same time.

The MSH01 movement is the hand-wound caliber and the MSA01 is the automatic version. The various Circularis models are all equipped with this outstanding technology. Their appliquéd hour numerals and their polished stainless steel cases provide the appropriate grandeur.

The new Circularis Automatic “Old Radium” has a completely different look, more casual and altogether cool. Its case is finely matted, giving it a more leisurely look than a highly polished surface. Here the hour numerals on the black dial are not appliques, but treated with “Old Radium” luminous paint, just like the single hand, creating the impression that the dial has gained a dignified patina over a period of decades. The face of this model is therefore reminiscent of the historical scientific measuring instruments that have always inspired the design of the MeisterSinger collection.

The Circularis’ MSA01 automatic movement follows the grand tradition of Swiss watchmaking, whose specialists have long mastered the art of finding mechanical solutions for every new technical challenge. One of MeisterSinger’s strict design specifications was that the hand should rotate extremely smoothly and evenly, despite its length.

To achieve this feat, the developers created a movement with a wheel with sprung teeth that minimizes the backlash of the hand. Two in-line mainspring barrels store the energy required for the unusually long 120-hour power reserve. The two barrels are powered by a tungsten rotor, which converts the wearer’s every arm movement into the energy that drives the movement.

Sickle-shaped recesses are reminiscent of MeisterSinger’s fermata logo and allow a good view of the movement at all times. With its meticulous ornamentation and the uniquely designed bridge, it also meets MeisterSinger’s most stringent aesthetic requirements and has already won the German Design Award for the hand-wound version.

The movement of the Circularis can be viewed through a screwed exhibition glass back.

The stainless-steel case is 43 millimeters in diameter and water-resistant up to a pressure of 5 bar. The watch comes with a vintage saddle leather strap.
