Royal Oak Perpetual Calendar 41 Steel Blue Dial

A Calendar Good Until 2100.

Day, date, month, week number, leap year and astronomical moon, laid across a blue Grande Tapisserie dial in steel. The calendar accounts for month lengths and leap years on its own and will not need correcting this century.

Six indications on one dial and it still reads at a glance, which is the harder half of the problem.

A grail piece for the discerning collector.
