The automatic watch of AP included a 21 carat gold rotor placed in the center. Their "Royal Oak" series was produced in 1972 and is considered to have created the market for the stainless steel luxury watch. It was designed by Gerald Genta.
Today the company, along with Patek Philippe and Vacheron Constantin, is sometimes claimed to be one of the top three Swiss watchmakers. Every timepiece manufactured in-house is still made using the old-fashioned hand-made technique.
This early Royal Oak is 18K solid gold massive huge watch, with "AP" was imprinted on the lower portion of the dial, instead of set at the 12 o'clock position as on the later design. Very Rare!
