WatchCharts’ Overall Market Index rose 0.1% in March 2026, with Patek Philippe gaining 1.2%, Grand Seiko 1.0% and Glashütte Original 0.8%. Rolex fell 0.3%, ending three consecutive monthly gains. Twenty of 27 tracked major brands advanced, versus eight a year earlier; more than 70% posted positive first-quarter performance, compared with 3% a year before.
Why it matters (interpretation): The widening share of brands posting gains suggests the secondary-market recovery is spreading beyond its early leaders, despite nearly flat aggregate prices in March.
