The Circularis line combines minimalist design and masterful watchmaking. The watches in this series are powered by movements developed especially for the MeisterSinger brand by SynergiesHorlogères. These are machines marked MSH01 and MSA02. The manual caliber MSH01 was introduced first, its automatic variant MSA02 then in 2016. Both machines have a wind reserve of up to 120 hours, which is ensured by two coupled feathers, which we can watch together with decorated bridges through a transparent pumpkin.
