Rolex Datejust | 36mm White "Wide Boy" Dial | Ref 1603 | 2.53M (1970) I

The Rolex Datejust Ref. 1603 is a classic vintage Datejust configuration, combining a 36mm stainless steel Oyster case with the distinctive stainless steel engine-turned bezel. It carries the timeless proportions that made the Datejust one of Rolex’s most recognizable models, while offering a slightly sportier and more understated look than its fluted bezel counterparts.

The standout feature of this example is the white “Wide Boy” dial. Known for its broader hour markers and bold vintage presence, the Wide Boy dial gives the watch extra character while still keeping the clean, elegant Datejust aesthetic. The white dial keeps the watch bright and versatile, making it easy to wear daily while still feeling special to vintage Rolex collectors.

With its 2.53M serial, this piece dates to approximately 1970, placing it in a desirable vintage Rolex era. The combination of the white Wide Boy dial, stainless steel case, and engine-turned bezel gives this watch a strong vintage identity with a clean, collectible look.
