In keeping with its corporate traditions, Numa Jeannin is presenting a seifwinding «semi- squelette» design at this year’s Fair in Basle. It features a 21-jewel ETA 2892 calibre. The dial and mainplate have been cut out to provide visual access to the balance wheel, enhancing the design’s attractiveness in the process. Its 10-micron goldplated case is water-resistant to 30 m and fitted with a flat mineral crystal as well as a see-through mineral glass aperture in the bezel.
