Louis Erard once again collaborates with Massena LAB - this time with a monopusher chronograph that draws inspiration from 19th century watchmaking, while maintaining progressive aesthetics. With a single pusher to start, stop, and reset the chronograph, Le Chronographe Monopoussoir Louis Erard x Massena LAB maintains a straightforward functionality while exemplifying technical prowess. 

A limited edition of 100 pieces
Ref. 74239AA71.BVA103

The gilded dial, with its grained finish, shines with every turn of the wrist and is handsomely contrasted by the rhodium-plated outer flange and counter. Inside, the Sellita SW500MPCa calibre keeps time running smoothly with a ~48 hour power reserve. The reverse of the watch provides a clear view of the mechanics through the sapphire glass exhibition caseback. This follow up to the Le Régulateur x Massena LAB collaboration again expresses the mastery of fine watchmaking, with elegant and thoughtful details, while maintaining accessibility.
