The series is known for its traditional classical face, a domed glass with a retro feel, and delicate case design with slender lugs. The new models feature an entirely new design adopting the popular roman numeral indices in six positions. It also features a dial indicating the day at 10 o’clock, a 24-hour indicator at 5 o’clock, and a date window at 3 o’clock. The five hands of the multi-hand display and dual markers on the outer rim of the dial result in a dynamic design adding a new charm to the Classic and Simple Style series.

These updated Classic and Simple Style models are powered by an automatic in-house calibre F6B22 (with hand winding) and show the time as well as calendar. The stable accuracy ranging between ＋25 seconds to－15 seconds per day, coupled with a 40-hour power reserve, make them ideal for everyday use.
