This rare Rolex from 1917 – 9ct gold, tonneau case with decentralised seconds – is a great example of the brand’s earliest wristwatches and the craftsmanship that helped shape its reputation. Set in a well-preserved 9ct yellow gold tonneau case, it reflects the elegant style of the early 1900s. The watch features a Roman numeral dial with a small seconds subdial, powered by an early manual-wind Rolex movement. It’s a beautiful snapshot of Rolex’s early design and engineering.
