Rolex has been manufacturing watches with 34mm case diameters for the majority of their long and distinguished history; however, these “mid-size” models such as the Date and Air-King often get overlooked due to the multitude of options that exist in the more standard, 36mm Rolex Oyster Perpetual case size. However, Rolex has manufactured a number of excellent watches – both vintage and contemporary – that have 34mm case diameters, and their highly versatile size allows them to look at-home on wrists of virtually any gender or measurement.Although the Datejust collection has historically had a case diameter of 36mm for the standard full-size model, Rolex also manufactures a line of watches called the Date that offers many of the same design traits and features of the Datejust – even the same movement too – only in a slightly smaller overall package.One of the most “quintessentially Rolex” watches currently in production with a 34mm case diameter is the reference 115234 Date. With a Cyclops magnification lens, stainless steel Oyster bracelet, and 18k white gold fluted bezel, the reference 115234 Date checks all the same design boxes as the Datejust, just with a slightly reduced size. Additionally, since the 34mm Date and the 36mm Datejust share the same movement, the reference 115234 is in no way a “lesser” watch compared to the Datejust, just one that is 2mm smaller.Since consumer trends favored smaller wristwatches in past decades, a number of great vintage Rolex references exist with 34mm case diameters. One of the longest-running Rolex models of all time is the reference 5500 Air-King, which boasts a super clean and minimal dial design that perfectly complements its slightly reduced case size.The reference 5500 remained in production for thirty-seven years, during which time it was fitted with both Rolex’s Caliber 1520 and Caliber 1530 movements – neither of which were chronometer-certified. Due to their long production run, reference 5500 Air-King watches were manufactured in relatively large numbers and can still be purchased for very reasonable prices. Fitted with one of the cleanest and least text-heavy dials found inside any Rolex watch, the Air-King 5500 pre-dates the widespread implementation of chronometer-certified movements and represents one of the best entry points into vintage Rolex collecting.Although the Day-Date President is the classic all-gold Rolex watch, it has never been manufactured in a size smaller than 36mm. However, throughout its history, Rolex has produced a number of all-gold watches within their Date collection that have 34mm case diameters, and lack the additional complication for displaying the day of the week that is found on the flagship Day-Date line of watches.One of the more modern incarnations of the all-gold 34mm Date is the reference 15238, which stands out due to a number of characteristics that help separate it from previous iterations of Rolex’s all-gold 34mm Date watch. While earlier examples were made from 14k gold, there reference 15238 is craft from 18k – the same as what Rolex uses to manufacture their flagship Day-Date President watch. Additionally, the Date 15238 is fitted with Rolex’s Caliber 3135 movement and a synthetic sapphire crystal, which give it all the ingredients necessary to be a fairly modern watch.
