ARF Rolex DateJust 31mm m278274-0018
ARF sets the benchmark in the mid-size Datejust category through exceptional 904L steel finishing and highly accurate case proportions.
Powered by Clone 2236
The clone 2236 caliber is engineered specifically for the smaller 31mm architecture, delivering a robust beat rate and dependable date complication. It features a bidirectional winding rotor and stop-seconds functionality for precise time setting. Before dispatch, all mechanisms are evaluated against to ensure optimal amplitude and long-term reliability.
Standard clone base regulation: typically 卤10��15 seconds per day.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Instantaneous date with rapid setting, stop-seconds
- �� Winding Direction: Bidirectional
Technical Specifications
Exact 10.2mm thickness, refined lug profile, and precise brushed to polished surface transitions.
Correct Chromalight application, crisp coronet detailing, and precise typography printing.
High-polish finish mimics white gold reflections with sharp, accurate fluting angles.
Five-piece link construction, solid end links, and tight folding clasp tolerances.
Why ARF for This Reference?
Many collectors ask: ��Why not GMF?��
While GMF produces a respectable 31mm variant, ARF excels in achieving the precise 10.2mm case thickness and superior bracelet finishing. The tactile feel of the ARF Jubilee bracelet and the refined tolerances of the folding Oysterclasp offer a more authentic experience on the wrist.
Full Disclosure: The automatic winding rotor on the clone 2236 can be slightly noisier than the genuine movement during vigorous wrist movement.

Collector Q&A
Q: How does the green dial color on this ARF 31mm compare to the genuine m278274-0018?
A: ARF has achieved an impressive sunburst effect that shifts tones dynamically in natural light. While the genuine Rolex mint green has a microscopic metallic depth that is difficult to perfectly replicate, this ARF batch captures the correct hue and saturation under most lighting conditions.
Q: Is the fluted bezel made of solid white gold like the authentic model?
A: No, the fluted bezel on this replica is crafted from highly polished 904L Oystersteel. While it mimics the light-play and visual dimensions of the genuine white gold bezel, it lacks the specific density and slightly warmer tone of precious metal.
Q: Does the date wheel feature the correct magnification and font?
A: Yes, the sapphire crystal is fitted with a 2.5x Cyclops lens that provides the correct magnification. The date wheel font is properly centered and mimics the authentic Rolex typography, though minor variations in ink thickness may be visible under a loupe.
Q: What is a known quirk of the clone 2236 movement in this 31mm model?
A: The automatic winding rotor on the clone 2236 caliber can be slightly audible during rapid wrist movements. A professional horologist can often mitigate this characteristic noise by applying a minimal amount of Moebius 9010 oil to the rotor bearings.
