The Annual Calendar is a great complication. While a regular mechanical calendar watch needs an adjustment on every month with less than 31 days, the Annual Calendar makes the 30-31 distinction and only needs an adjustment in February. It does not command the high prices of a perpetual calendar, while it is mechanically interesting and hardly less functional. The caliber 8611 is based on the wonderful 8501 and shares the same intricate finishing - of course fitted with a solid gold rotor.
