The 5502 and the 5506 are the gold-capped Cal 1530 Super Precision Air-King reference pair — parallel-production siblings that ran from approximately 1958 through 1964/65. Mechanically identical: 34mm Oyster case with 40 microns of yellow gold electroplate over a steel base, smooth gold-capped bezel, gold-capped Twinlock crown, acrylic plexiglass crystal, Cal 1530 Super Precision throughout (25 jewels at 18,000 vph), "AIR-KING / SUPER PRECISION" dial text, alpha hands and applied gold indices. Both reference numbers ride on the same Kessi Frères SA case construction with the characteristic KB tombstone hallmark inside the caseback, and both ship on the 78351 gold-capped Oyster bracelet. | The 5502 and the 5506 are the gold-capped Cal 1530 Super Precision Air-King reference pair — parallel-production siblings that ran from approximately 1958 through 1964/65.
