This new addition to the Masterpiece collection marks the return of one of Maurice Lacroix’s specialities. Indeed, retrograde displays have been part of the company’s DNA since 1999. At this time, the Masterpiece collection was already part of the company’s catalogue. The rationale for the collection was to showcase the brand’s know-how. It called upon traditional skills such as skeletonization and knowledge of complications that were uncommon at the time. Maurice Lacroix used retrograde displays to reinforce its brand personality. From the outset, the brand developed specific display modules for functions. It demonstrated visionary thinking founded on technical innovation without ever losing sight of the lifestyles of its clients. This gave rise to the Maurice Lacroix Calendrier Rétrograde at the turn of the 21st century.
