ARF Edition — Jubilee Bracelet
The ARF iteration of the Datejust 31mm reference 278383RBR establishes a strict horological benchmark for mid-size replicas, specifically noted for achieving an exact 10.4mm case thickness. Weighing in at 83.6 grams, this model effectively balances the density of its 904L Oystersteel core with the visual profile of its two-tone construction, offering a highly precise alternative for collectors evaluating mid-size proportions.
At the core of this piece operates the Clone 2236 caliber, a mechanical self-winding movement engineered to replicate the beat rate and functional architecture of the authentic Rolex mechanism. While it lacks the free-sprung balance of the genuine article, it provides reliable daily performance and instantaneous date switching. Power reserve is rated at approximately 36 hours.
The case and Jubilee bracelet are machined from premium 904L Oystersteel, finished with an 18k yellow gold plating that presents a rich contrast against the olive green sunray dial. The dial features a meticulously applied diamond-set Roman VI numeral, sitting beneath a sapphire crystal equipped with the signature 2.5x Cyclops lens and correct anti-reflective coating.
