Description
ARF Rolex DateJust 31 Ref. 278384RBR Jubilee
A highly precise 31mm execution featuring ARF��s signature 904L steel finishing and a dedicated Clone 2236 caliber.
Powered by Clone 2236
The mechanical core of this 31mm Datejust is the Clone 2236, a caliber developed specifically to accommodate the smaller case dimensions without sacrificing reliability. Unlike standard ETA 2824 adaptations, this movement features correct crown stem heights and instantaneous date jumping at midnight. Before dispatch, all mechanical components are verified through to ensure proper amplitude and beat error tolerances.
The Clone 2236 typically yields an accuracy of 卤10��15 seconds per day, operating at a 28,800 vph beat rate.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Instantaneous date with rapid setting, stop-seconds for precise time setting
- �� Winding Direction: Bidirectional self-winding via perpetual rotor
Technical Specifications
Measuring exactly 31mm in diameter and 10.2mm thick, the case profile mirrors the genuine article, complete with high-polish flanks and a screw-down case back.
The dial exhibits a refined sunburst effect, complemented by Chromalight-filled applied indices and sharp, correctly weighted text printing.
The fixed bezel is intricately set with cubic zirconia stones, precisely aligned to replicate the light play of a factory diamond bezel.
Features five-piece solid links with alternating brushed and polished finishes. The folding Oysterclasp snaps securely with minimal endplay.
Why ARF for This Reference?
Many collectors ask: ��Why not GMF or BPF?��
While GMF produces a reliable 31mm Datejust, ARF remains the undisputed leader in 904L steel processing and bracelet fabrication. The tactile feel of the ARF Jubilee bracelet, combined with the incredibly tight tolerances of the solid end links against the 31mm case, provides a wearing experience that rival factories struggle to match.
Full Disclosure: The Clone 2236 rotor can be slightly more audible than the genuine caliber during rapid wrist movements, a common trait in compact clone movements.

Collector Q&A
Q: Is the diamond bezel on this ARF 278384RBR made of real diamonds?
A: No, the ARF factory uses high-quality cubic zirconia (CZ) stones to simulate the genuine factory-set diamonds. They are cut and set to reflect light similarly to the authentic piece, but they are not genuine moissanite or natural diamonds.
Q: How accurate is the Clone 2236 movement in this 31mm case?
A: The Clone 2236 operates at 28,800 vibrations per hour (vph) and typically yields an accuracy of 卤10��15 seconds per day out of the box. It is specifically designed to fit the 31mm mid-size case while maintaining correct date-jump mechanics.
Q: Does the Jubilee bracelet fit genuine Rolex spring bars?
A: Yes, ARF is renowned for its precise 904L Oystersteel fabrication, and the end-link tolerances on this 31mm model allow for the installation of genuine Rolex spring bars without modification.
Q: Is the winding rotor noisy on this specific caliber?
A: As with many compact clone movements, the 2236 can exhibit slight rotor noise when the wrist is flicked rapidly. A light application of Moebius 9010 oil during a standard movement service mitigates this issue entirely.
