This Jaquet Droz Astrale reference J024038201 is a limited edition, and in this form it gives the line a distinctly darker register. Its automatic movement drives the chronograph, while the grande date named in the model gives the watch a more uncommon calendar display than the usual aperture. In stainless steel, the case measures 43mm across and 14.2mm thick, which gives it the broad proportions this design wants. The black dial keeps that monochrome approach intact, letting the layout read with more severity than flourish. For a collector drawn to Jaquet Droz outside the firm's better known enamel pieces, that makes this a notably different proposition within the house's output. Limited to 88 pieces, it stands apart as a more contemporary reading of the Astrale, one that shifts the emphasis from decorative tradition toward contrast, scale, and complication.
