Audemars Piguet Pocket watch Royal Oak

AP Royal Oak Pocket
Two gold - This model is part of the long tradition of Audemars Piguet pocket watches, which has its roots in the 19th century. During the 1960s and 1970s, many variations of ultra-thin watches were created in very small series, which were sometimes round in shape, but often polygonal, hexagonal and even octagonal. Model 5691 (renamed 35691 in 1984-85) was the first to interpret the Royal Oak as a pocket watch. The eight non-cross-through hexagonal screws punctuate the bezel as well as the chain links. It is worth noting that the sword-type hands and hour-markers have no luminescent material. The Production Registers mention at least 43 two-tone examples, sold between 1980 and 1982. Unlike the very first two-tone Royal Oak watches, which combine steel and yellow gold, Model 5691CA combines white and yellow gold. This association of different gold colours is also interpreted on the chain. The letters "CA" are a contraction of "BC" (white gold) and "BA" (yellow gold). Sales from 1980 to 1982: 43 units in all, of which 14 (1980), 28 (1981), and 1 (1982) This one in particular is unique because of its characteristic crown positioned at 3 o'clock. The object is worthy of a museum, being the rarest model of the 43 ever produced.
