1975 Master Grand Date Retrograde Unique Piece for ELA 2026

Maurice Lacroix dedicates a unique 1975 Master Grand Date Retrograde to the European Leukodystrophy Association (ELA), uniting fine watchmaking with a meaningful cause. Its 42mm stainless steel case frames a transparent sapphire dial, punctuated by distinctive pink accents symbolising hope and solidarity.
