The Sollen SL502 Automatic Watch merges contemporary technical layout with traditional open-heart mechanics. Built with a 42mm solid stainless steel chassis weighing 166g, this premium timepiece houses an authentic Seiko NH39A automatic caliber, featuring a 4-hand multi-function configuration visible through an exhibition caseback. Protected by a flat scratch-resistant sapphire crystal lens, the hydraulic sunburst copper dial highlights a dedicated 11 o’clock 24-hour register alongside a striking 10 o’clock open-heart skeleton flywheel. Completed with custom skeleton hands and a fluid 7-bead solid link bracelet with a double-press butterfly clasp, it offers an uncompromised professional statement.
