Rolex Datejust 31 Yellow Gold — Silver Jubilee Diamond Dial, Fluted Bezel | Ref. 178238

Reference 178238 is the Datejust 31 in full yellow gold — a proposition that sits between the 28mm Lady-Datejust and the 36mm standard Datejust in size, but reaches toward the prestige of a full precious-metal watch. The fluted bezel in solid gold, combined with a silver dial set with diamond hour markers in Jubilee style, creates a watch that is simultaneously classic in form and genuinely luxurious in material specification. This configuration was produced under the 178xxx reference system before the current 278xxx generation.

The 31mm case in 18ct yellow gold wears the fluted bezel to maximum effect — the ridged gold surface catches ambient light and creates the impression of greater size than the measurement alone would suggest. Inside, the watch is powered by Calibre 2236, incorporating Rolex's Syloxi silicon hairspring for enhanced magnetic and thermal resistance, with a 55-hour power reserve. The President bracelet in solid yellow gold — the exclusive bracelet of the Datejust 31 and Lady-Datejust in precious metal — is one of Rolex's most accomplished bracelet designs, with semi-circular three-piece links that drape the wrist naturally.

Full yellow gold 31mm Datejust references with diamond dials occupy a durable position in the pre-owned market. The Jubilee diamond dial configuration is particularly sought after — it pairs the intrinsic value of set stones with a design language that connects directly to the Datejust's 1945 heritage. Buyers prioritising a full-gold ladies' Rolex at a more accessible size than the Day-Date 36 frequently arrive at references like the 178238 as the ideal balance of substance and wearability.
