Rolex Day-Date 36 ‘Wide Boy’ – Ref. 1803 – Circa 1977

An icon of Rolex’s vintage catalogue, this 18ct yellow gold Day-Date is presented in one of the reference’s most desirable configurations.

Produced circa 1977, this reference 1803 features the sought-after champagne ‘Wide Boy’ dial, distinguished by its oversized baton hour markers and matching broad hands. Combined with the classic fluted bezel and warm yellow gold case, it embodies everything that has made the early Day-Date one of Rolex’s most enduring and collectable references.

Complementing the watch is a brand new Molequin grey leather strap, finished with a brushed gold-tone buckle and quick-release spring bars, allowing effortless strap changes while providing a refined, contemporary finish.

Powered by Rolex’s automatic chronometer-certified movement with both day and date complications, this is a beautifully presented example of one of Rolex’s most iconic vintage references, equally suited to regular wear or a discerning collection.
