With its pure, timeless elegance, this stainless-steel Master Ultra Thin automatic watch adorns the slimmest of wrists with its 38.5 mm diameter. The watch is like a second skin or an extension of the body, and slipping it on soon becomes second nature. The Master Ultra Thin Small Second watch's sapphire crystal case-back is a true open window on its automatic movement with its delicately-worked finish. This watch's understated refinement is emphasized not only by the ethereal lines of its case and dial, but also by its hands and hour-markers. The interplay of light on the watch's silvered dial creates delicately soft, satin-smooth reflections. Meanwhile the small seconds dial at six o'clock has a subtly different light effect thanks to its guilloché-patterned surface.
