This 1979 Rolex Air-King (ref. 5500) bears a co-branded dial with the Pool Intairdril Logo. The Pool Intairdril watches are quite rare as they were produced by Rolex in the late 1970s into the early 1980s for Pool Intairdrill which was an oil servicing company. Pool Intairdrill supplied the labor, rigs, plants, etc to the big named oil companies, ie Oxy (Occidental), Agip, and the Libyan NOC (National Oil Company). These watches were given to Pool Intairdril employees typically as safety awards. Safety was a huge issue, each rig was proud of its run of accident-free days and rig managers and other personnel in charge of safety management would be given the Rolex Air kings with their names engraved into the case back along with a certificate of commendation.
