Unlike modern iterations, the 25654BA lacks a leap year indicator on the dial, a characteristic of early AP perpetual calendars. Approximately 422 units were manufactured in 18k yellow gold. On the secondary market, these timepieces typically trade in the $100,000 to $160,000 range depending on the presence of original paperwork and dial condition.
