Here is a very rare watch. This is a the FIRST version of the Rolex Air-King dating to 1945 and all original. During the 40’s, round Rolex watches were generally small-in the 30-32mm. range. Some of the dress watches up to 36mm. (rare). This watch measures a respectable 34mm. (like the later Air-Kings) in stainless steel with original winding crown. These are slim watches with narrow bezel and look a little smaller than the 70’s Air-Kings. The Roman dial is amazing and original including the luminous. The blued steel pencil hands are original including the lume. This fine manual winding Rolex movement was recently cleaned-sparkling and accurate. The original Rolex stretch and riveted bracelet is British made WAB (Watch Accessories Birmingham) was owned by Oscar Winter, a friend of Hans Wilsdorf. These bracelets appear on the very early Rolex watches and were produced to circumvent import duties. This Rolex bracelet will fit up to a 6.75 inch wrist. This is a damn rare watch.
