First introduced in 1945, Rolex’s DateJust has remained one of the most recognizable watches over the past several decades. It’s known as the modern prototype of the classic watch and has a versatile, timeless style that can be dressed up or down to wear anywhere. To cater to women with smaller wrist sizes, Rolex introduced the Lady-DateJust in 1957 that offered smaller sizes including 26 mm and 28 mm.
