Maurice Lacroix, renowned for over 25 years of retrograde complications, unveils its 26th Masterpiece calibre: the 1975 Master Grand Date Retrograde. This model features a retrograde day indication, grand date, and a striking skeletonised display. Combining technical mastery with aesthetic precision, it offers exceptional readability through an expansive sapphire crystal. The skeletonised dial reveals components usually hidden, including a sandblasted, black-rhodium-treated mainplate and rhodium-finished bridges. Trapeze-style hands with Super-LumiNova® enhance legibility, while a rhodiumed flange frames the display. With this timepiece, Maurice Lacroix continues to reinterpret retrograde indications, marrying heritage, functionality, and contemporary watchmaking innovation.
