Introduced in 1978, the reference 18038 shares a striking resemblance to its predecessor, the reference 1803, while incorporating several noteworthy technical advancements. Notable improvements include an increased water resistance, the introduction of a sapphire crystal—an inaugural feature for the Day-Date collection—and the implementation of the new calibre 3055 movement. This upgraded movement operates at a higher frequency of 28,800 vibrations per hour and introduces the convenient quickset mechanism for the date function.

Available in a variety of dial options, including Stella dials, hard stone dials, and metal dials with various designs, the reference 18038 also showcased the creative prowess of Rolex by featuring wooden dials, as seen in the present example. The incorporation of organic wooden dials brings a refreshing aesthetic to the wristwatch, juxtaposing the technical nature of the timepiece with the natural allure of the wood's unique grain patterns. Each wooden dial is inherently one-of-a-kind, ensuring that no two dials will ever possess the exact same appearance.

The current model boasts a stunning 'golden walnut' wood dial, and due to the natural characteristics of wood, each dial possesses its own distinct identity, making it truly unique in its visual presentation.
