The SL306 Automatic Mechanical Watch artfully organizes advanced multi-functional complications into a unified, balanced dial. Protected by a flat mineral crystal featuring a subtle blue anti-reflective coating, it brings together a dual-time register at 9 o'clock and a synchronized moon phase combined with a unique 120-second sub-dial at 3 o'clock. Balanced perfectly by the constant pulse of an open-heart flywheel at 6 o'clock, this self-winding timepiece offers continuous precision for the modern collector.
