MeisterSinger premium-line watches feature technically outstanding movements that have been specially developed to meet the requirements of single-hand watches. The Circularis Power Reserve is the first model to include a special complication on the dial – a semi-circular power reserve display positioned at 9 o’clock. The MSH02 hand-wound movement stores sufficient energy in two mainspring barrels for 120 hours of precision timekeeping. A specially designed differential calculates the remaining power from the difference between the revolutions of the two mainspring barrels and indicates when the watch needs to be rewound.
