It is a masterpiece that is also known by the unique nickname "UFO" among Bellmatics. The large 42mm cushion-shaped case has a striking design reminiscent of a flying saucer. The automatic winding alarm mechanism of Caliber 4006 brings out the unique taste of a mechanical watch. The clean design is also attractive, with the enlarged alarm indicator ring taking up most of the dial. This is a masterpiece that stands out among the Bellmatic lineage that started in 1966 and is coveted by collectors. The alarm mainspring can be wound by winding the crown at 3 o'clock, and the mainspring can be wound automatically.
