Description
ARF Rolex DateJust 31mm Ref. 278243-0028 Rolesor
A mechanically precise, mid-size replication utilizing ARF��s benchmark 904L Oystersteel finishing.
Powered by Clone 2236 Caliber
The 31mm DateJust requires a specialized compact mechanism, fulfilled here by the Clone 2236 automatic movement. It replicates the operational crown positions of the genuine caliber, allowing for crisp instantaneous date changes. Before dispatch, all movements are evaluated against to ensure amplitude and beat error remain within acceptable tolerances for a daily wearer.
Regulated to approximately 卤10��15 seconds per day, standard for compact clone architectures.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Instantaneous date with rapid setting, stop-seconds
- �� Winding Direction: Bidirectional
Technical Specifications
Measuring exactly 31mm across and 10.8mm thick, the Monobloc middle case features correct lug tapering and polished flanks.
The sunray finish reflects light dynamically, while the faux-diamond hour markers mimic the factory settings with reasonable depth and clarity.
The fluted profile catches light effectively, though the 18k yellow gold plating lacks the absolute mass and warmth of solid gold.
Five-piece links with solid end-links, secured by a Folding Oysterclasp. ARF��s signature tight tolerances prevent excessive bracelet stretch.
Why ARF for This Reference?
Many collectors ask: ��Why not GMF or BP?��
While GMF produces excellent mid-size models, ARF is widely recognized for superior 904L steel finishing and tighter bracelet tolerances. The end-link fitment against the 31mm case on this ARF version presents noticeably less play than its competitors, yielding a more premium tactile feel.
Full Disclosure: At 90.4 grams, this piece is significantly lighter than the genuine two-tone model, as the gold-plated steel center links cannot replicate the density of solid 18k gold.

Collector Q&A
Q: How does the 18k yellow gold plating on the ARF Jubilee bracelet hold up to daily wear?
A: The plating is applied via PVD, which is highly durable for standard office wear. However, because it is a surface treatment over 904L steel, it will eventually reveal the lighter steel underneath if heavily scratched or exposed to abrasive chemicals.
Q: Are the diamond hour markers on the olive green dial moissanite or cubic zirconia?
A: ARF uses high-clarity cubic zirconia for the hour markers on this reference. While they catch ambient light effectively, they lack the specific refractive index of genuine diamonds or aftermarket moissanite stones.
Q: Does the Clone 2236 movement accept genuine Rolex parts?
A: While the architecture mimics the genuine 2236 to fit the 31mm case properly, it is not a true 1:1 super clone regarding parts interchangeability. Most genuine internal components will not fit without significant modification by a watchmaker.
Q: Why does this replica weigh 90.4 grams when the authentic DateJust 31 two-tone is heavier?
A: The genuine reference 278243 utilizes solid 18k yellow gold for the fluted bezel and Jubilee center links. This ARF replica uses gold-plated 904L steel, which lacks the density of solid gold, resulting in a noticeably lighter overall mass.
