Calibre 4400

This hand-wound movement embodies an ideal balance between a determination to innovate and respect for traditions. It is distinguished by its 12.5’’’ (28.60 mm) diameter perfectly suited to contemporary cases. Thanks to its imposing barrel devised and developed by the Research & Development department, it provides an appreciable 65-hour power reserve. This simple and well-finished calibre is fully compliant with all Hallmark of Geneva criteria.
