The Rolex Datejust reference 178344 is a 31mm timepiece in Steel presented in used condition, with a White MOP Roman Diamond IV dial, Diamond bezel, Oyster bracelet. This piece is customized — aftermarket-modified (setting or dial added outside the manufacturer); not original factory condition. Every watch is inspected and authenticated by our specialists before it is offered, so you can buy with confidence.
Introduced in 1945, the Datejust was the first self-winding waterproof chronometer to display the date beneath a magnified Cyclops window, a defining Rolex innovation. It spans four case sizes, multiple metal combinations, and an almost unlimited dial palette, which makes it Rolex's most accessible yet most versatile reference. Think of it as a dress-capable daily wearer with collector heritage, and lean on in-house authentication before you buy with confidence. Read the full Datejust buying guide ›
Hans Wilsdorf founded Rolex in 1905, and the Geneva manufacture has since become the benchmark against which most mechanical watches are judged. Its engineers pioneered waterproofing, self-winding movements, and date displays, building a reputation for precision and durability. Before you buy, our desk verifies the Oyster case, the Perpetual movement, and the Cyclops lens. With supply trailing demand, steel sports references often trade above retail, so confirmed authentication matters. Browse all Rolex ›
