DB28

Digitale

Reference: DB28DN / S

The DB28 Digitale, equipped with a mechanism powering multiple display modes – digital for the jumping hours and analogue for the minutes and spherical for the moon phases – embodies a highly contemporary vision of the aesthetic of that era. The dial adorned with a hand-guilloché barleycorn motif, together with the spherical moon and the star-studded sky, represent classical references that are arranged and executed in a manner that accentuates the modernity of the design.
