Things to Know About the Rolex Oyster
Rolex calls the Datejust "the pillar of the Oyster collection." Since 1945, the first self-winding Rolex chronometer has been globally recognized for its sleek but sturdy design, precision, and durability. Whether your choice is a Rolex Oyster Perpetual Datejust Diamond or a steel Rolex Datejust 1977, you can find both of these vintage watches on eBay.Rolex Oyster Perpetual Datejust Name Meaning
Oyster means that the watch uses the Rolex Oyster case, which is waterproof. Perpetual refers to the self-winding mechanism that keeps the watch running without batteries or other external methods. The Datejust refers to the calendar date in place of the 3 on the watch face. For watches made after 1953, the date is under a cyclops bubble that magnifies it 2.5x.What characteristics does the Rolex Oyster Perpetual Datejust have?
The Rolex Oyster Perpetual Datejust uses the famous Rolex Oyster waterproof case, first introduced in 1926. The Oyster case is made from 904L stainless steel, 18K gold or platinum and comes in a range of diameters, from the Lady Datejust at 28mm to the heftier Rolex Oyster Perpetual Datejust at 41mm. Each case model comes with a choice of faces, either simple hour bars, Roman numerals, or Arabic numbers. Some faces have custom motifs, such as the flower-bedecked floral. Bezels come in a variety of styles, from simple steel-and-white gold to fluted steel to diamond-encrusted. Metal bands come in standard or smaller piece "Jubilee" styles.Size and Movement Options for the Rolex Datejust
The ladys watch face versions of the Datejust are 28mm, 31mm, 34mm and 36mm diameters. The mens Datejust comes in 41mm and 36mm versions. While Rolex produces manual-wind and quartz movements, all Rolex Oyster Perpetual Datejust movements are self-winding. The current movement for a Datejust is Rolexs top-of-the-line Caliber 3135.How is a Rolex Datejust different than a Rolex Date?
The primary difference in a Rolex Datejust vs a Rolex Date is how the calendar date is advanced. On a Rolex Datejust, pulling the crown out halfway allows you to advance the date. Older Rolex Date models advanced one day by rotating the hour hand 360 degrees per day. Now both watches share the same Caliber 3135 movement. One remaining difference is the Dates 34mm mens watch, which is smaller than the Datejust. The bracelet on a Datejust is also 20mm wide instead of 1 mm for the Rolex Date.Content provided for informational purposes only. eBay is not affiliated with or endorsed by Rolex.
