The Maurice Lacroix Masterpiece | family history

The Masterpiece line dates to 1994 and has always been Maurice Lacroix's opportunity to compete on mechanical invention rather than brand prestige. The standout piece is the Seconde Mysterieuse: a jumping-seconds display where the seconds hand appears to float without visible connection, accomplished via magnetic coupling between two coaxial discs. It is a patented mechanism, not a visual trick, and it functions reliably across thousands of reported service cycles. At the Masterpiece price point, no other brand offers this level of mechanical novelty in production.

Year introduced: 19941 reference

Maurice Lacroix's high-end complication line from the Saignelegier manufacture. Includes the Seconde Mysterieuse (mysterious floating seconds), Calendrier Retrogrades, and Gravity tourbillon, at prices that undercut Geneva houses. For buyers who want serious watchmaking at Zenith/Frederique Constant price levels rather than JLC/Blancpain.

1994 · Masterpiece launch and complication philosophy

Maurice Lacroix introduced the Masterpiece as a halo line to compete against Frederique Constant and lower-tier IWC on horological invention. Early pieces featured moon phases and power reserve displays executed in the brand's characteristic oval-case dress format. The line established Maurice Lacroix's identity as a brand willing to build unusual complications at non-Patek price levels.

2004 · Seconde Mysterieuse introduction

The Seconde Mysterieuse launched with a patented magnetic coupling mechanism that replaced the traditional seconds-hand gear train with a magnetically-driven floating display. The complication is genuinely novel: two discs coupled via opposing magnets allow the seconds hand to jump at each tick with no visible connection to the movement. This was the piece that established the Masterpiece as more than a decorated dress watch.

2010 · Gravity and further horological development

The Masterpiece Gravity arrived as the brand's entry into the tourbillon-adjacent legibility-focused complication space. A double-balance-wheel system separated by an arch visually referenced tourbillon architecture without the full complexity. The Masterpiece line has continued to add limited-edition complications while the Seconde Mysterieuse remains its most recognizable production piece.
