Description
ARF Rolex DateJust 31 m278381rbr-0016 �� Two-Tone Jubilee
ARF delivers the most dimensionally accurate 31mm mid-size case with superior bracelet end-link tolerances in the current market.
Powered by Clone 2236 Caliber
The Clone 2236 movement operates at 28,800 vibrations per hour, providing a smooth sweep for the seconds hand. Designed specifically to accommodate the smaller 31mm case architecture, this caliber avoids the stem-height alignment issues previously seen in generic ETA adaptations. The date mechanism features a rapid-setting function and instantaneous turnover at midnight, closely mirroring the functional behavior of the authentic mechanism. All movements are subject to prior to dispatch.
Standard factory regulation for the Clone 2236 yields an accuracy of approximately 卤10��15 seconds per day across varying positional variances.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Instantaneous date with rapid setting, stop-seconds
- �� Winding Direction: Bidirectional self-winding
Technical Specifications
Constructed with an 11mm thickness and weighing 83.1 grams, the monobloc middle case features high-polish sides and brushed lug hoods.
The dial exhibits a deep green base tone with crisp text printing and accurately proportioned hour markers coated with Chromalight-style luminescence.
Features a fixed bezel set with cubic zirconia stones, precisely aligned to replicate the gem-setting pattern of the genuine 278381RBR reference.
Five-piece link Jubilee bracelet with solid end links and a concealed folding Crownclasp, exhibiting minimal lateral play.
Why ARF for This Reference?
Many collectors ask: ��Why not GMF?��
While GMF produces a wide array of mid-size models, ARF holds a distinct advantage in 904L steel processing and bracelet assembly. The end-link fitment against the 31mm case on this ARF version is notably tighter, reducing the gap visible on lesser replicas. Furthermore, ARF��s polishing on the Oystersteel components yields a deeper luster.
Full Disclosure: The Everose gold plating on the center links can appear marginally warmer or more coppery under direct, harsh sunlight compared to solid 18k Everose gold, and the 2236 clone rotor is slightly audible in quiet environments.

Collector Q&A
Q: Does the Clone 2236 movement accept genuine Rolex parts?
A: While visually similar in architecture, the Clone 2236 differs dimensionally from the genuine caliber. It does not natively accept genuine Rolex internal components, though the dial and hands may be retrofitted with specialized horological modification.
Q: How accurate is the Everose gold plating on the ARF Jubilee bracelet?
A: ARF utilizes a high-quality PVD plating process. The tone closely mimics Rolex��s proprietary Everose alloy, though it can appear marginally warmer or more coppery under direct, harsh sunlight compared to solid 18k gold.
Q: Are the diamonds on the m278381rbr-0016 bezel genuine?
A: No. The factory utilizes high-grade cubic zirconia (CZ) handset into the bezel. They offer excellent light refraction and mimic the factory setting pattern, but do not possess the exact brilliance or hardness of genuine VVS diamonds.
Q: Is the rotor noise noticeable on this specific 2236 clone?
A: Yes, the automatic winding rotor on the clone 2236 is slightly more audible than the genuine caliber. A standard horological service involving proper lubrication of the rotor bearings can significantly mitigate this sound.
