Description
ARF Rolex DateJust 31mm m278273-0004 Two-Tone
AR Factory establishes the standard for mid-size DateJust replicas through meticulous 904L Oystersteel finishing and highly accurate Jubilee bracelet tolerances.
Powered by Clone 2236 Caliber
The mechanical foundation of this 31mm DateJust is the Clone 2236 automatic movement. Designed specifically for mid-size cases, this caliber features a compact architecture while maintaining essential genuine functions such as a quickset date and hacking seconds for precise synchronization. Every movement undergoes rigorous testing to meet before final assembly. The rotor utilizes a ball-bearing mechanism to ensure efficient bidirectional winding during daily wear.
The Clone 2236 movement is typically regulated to operate within 卤10��15 seconds per day, consistent with standard high-beat Asian clone calibers.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Centre hour, minute and seconds hands; instantaneous date with rapid setting
- �� Winding Direction: Bidirectional automatic winding
Technical Specifications
The 31mm case features a measured 10.6mm thickness, utilizing a monobloc middle case with a screw-down case back and winding crown. The alternating brushed and polished surfaces mirror genuine finishing techniques.
The dial exhibits a deep, rich hue with crisp text printing and correctly proportioned indices. Chromalight luminous material is applied to the hands and markers for low-light visibility.
The fluted profile catches light dynamically, though the gold plating tone may appear marginally warmer than solid 18k gold under harsh artificial lighting.
Featuring five-piece links, the Jubilee bracelet articulates smoothly without excessive lateral play. The folding Oysterclasp snaps securely with precise mechanical feedback.
Why AR Factory for This Reference?
Many collectors ask: ��Why not GMF?��
While GMF offers excellent mid-size options, ARF consistently delivers superior tactile feel on their Jubilee bracelets. The solid end links (SEL) on this ARF model sit perfectly flush against the 31mm case lugs, eliminating the micro-gaps occasionally found on rival factory batches.
Full Disclosure: The 18k yellow gold plating tone is slightly warmer than genuine, and the overall watch weight of 82.6g is lighter than the solid gold genuine counterpart.

Collector Q&A
Q: Does the Clone 2236 movement in this 31mm model accept genuine Rolex dials and hands?
A: While the case dimensions are 1:1, the Clone 2236 uses different hand pinion sizes and dial foot positions compared to the genuine Rolex caliber. Installing a genuine dial requires clipping the feet and using adhesive pads, and genuine hands will not fit the clone pinions.
Q: How durable is the 18k yellow gold plating on the ARF Jubilee bracelet?
A: AR Factory utilizes a robust PVD plating process for their two-tone models. With standard desk-diving wear, it resists fading exceptionally well, though deep scratches will inevitably reveal the base 904L Oystersteel beneath the center links.
Q: Is the 82.6g weight accurate to the genuine m278273-0004?
A: No. The genuine two-tone 31mm DateJust weighs approximately 95 grams due to the high density of the solid 18k gold center links and fluted bezel. The ARF replica, utilizing gold-plated steel, is noticeably lighter at 82.6 grams.
Q: What is the primary known quirk with the ARF 31mm DateJust?
A: The primary technical constraint is the rotor noise on the Clone 2236 movement. In a quiet room, the bidirectional ball-bearing winding mechanism is slightly more audible than the heavily insulated genuine Rolex caliber.
