At that time still a chronograph, today in 2020 it is a special puristic single-hand watch. Our new Squarematic impresses with a particularly elaborate manufactured square case with polished bezel and polished case flanks. Due to the moderate size of 39x39 mm, the watch case could still be classified in the unisex category.The dial with its hand-applied 3D indexes and fine sunburst finish is curved on the outer edges. This creates a special depth effect. The striking central hand was made in the design of a balance wheel.
