838S skeleton movement
Ref : 838S
An ultra-thin hand-wound movement measuring only 2.7 mm thick, the 838S skeleton movement is a variation of the 838P movement, from which it derives all its qualities. It boasts a balance with screws and an off-centered small seconds indication at 10 o'clock, a hallmark of Manufacture Piaget watchmaking. In a genuine technical feat for an ultra-thin movement, its bridges and its mainplate were drawn as far as possible, then guilloched, thus creating a uniquely refined design with a guilloché sunburst motif shining out from the center of the carriage, reminiscent of the sun's rays and the divisions of time. The extreme delicacy of its execution offers a detailed insight into the marvelous complexity of its workings to the admiring onlooker. This skeleton movement belongs to the third generation of ultra-thin movements from the watchmaker Piaget. The circular-grained mainplate and bridges, hand-drawn and beveled, and the blued screws round off this exceptional movement, while remaining true to the esthetic codes cherished by the Swiss watchmaking brand.
