Oyster perpetual意思

"Oyster Perpetual" is a term used by Rolex to describe a type of watch that is both waterproof and self-winding. The "Oyster" part of the name refers to the brand's iconic Oyster case, which was invented in 1926 and was the first truly waterproof watch case. The "Perpetual" part of the name refers to the watch's automatic movement, which winds itself using the natural movements of the wearer's wrist.

Rolex has used the Oyster Perpetual name on many of its models over the years, including the Submariner, the Explorer, and the Datejust. These watches are known for their durability, precision, and style, and are popular among both collectors and everyday wearers.
