The SL329 Steel Edition brings an architectural, celestial narrative to a highly resilient stainless steel chassis. Protected by a premium flat synthetic sapphire crystal mirror, its hydraulic sunburst dial intricately balances an elegant moon phase register at 12 o'clock with a unique rotating planetary moon disc at 7 o'clock. Anchored by the visible, continuous pulse of an open-heart flywheel at 6 o'clock, this 41mm timepiece transitions smoothly into an integrated 5-row solid stainless steel link band, delivering a commanding structural presence for the modern collector.
