Audemars Piguet 1980 Royal Oak Jumbo in 18k Gold fantastic condition. Today we have a very fine Audemars Piguet Royal Oak from the first series with the reference 5402BA from 1980. Finding a good one in steel is difficult enough, but finding a very good one in gold is almost impossible. The watch has been worn very rarely over the last 40 years and is in unpolished condition. The case is very well preserved for its age and the watch is a real pleasure to wear. The version with the champagne tapisserie dial and the logo at the bottom is the rarest and most expensive, but in my opinion also the most beautiful, which is not always the case. The strap has no significant loss of tension and fits wrists up to 16.5 cm in circumference. If this is too small, new links can be ordered from Audemars Piguet. The movement has been checked and oscillates at a powerful 265 degrees with minimal deviation. Audemars Piguet writes about the low production numbers: The yellow gold version introduced in 1977 was produced in a limited edition of 736 pieces and sold between 1977 and 1990. It is available in several dial variations, some with gemstone settings. Nine pieces were converted to the 4187 model with gemstone settings on the bezel. Number of pieces sold: 736 (including 9 pieces converted to the 4187 model between 1980 and 1985) Numbering 1 to 745 Sales period: 1977–1990, i.e. 95 (1977), 231 (1978), 122 (1979), 135 (1980), 51 (1981), 22 (1982), 19 (1983), 23 (1984), 9 (1985), 13 (1986), 3 (1987), 8 (1988), 3 (1989), 2 (1990) Accordingly, the number 595 shown here dates from 1980.
