BT Factory Rolex Daytona 116505 Everose Gold
A technically proficient 4130-powered chronograph distinguished by its accurate 12.2mm case thickness and superior crystal clarity.
Powered by Shanghai Cal. 4130
The Shanghai 4130 clone movement represents a significant horological achievement in the replica space, featuring a true column wheel and vertical clutch mechanism. This ensures the central chronograph seconds hand starts without the characteristic jump seen in modified 7750 calibers. The paramagnetic blue Parachrom hairspring replica provides dependable stability, while the KIF-style shock absorbers enhance durability during daily wear. Every piece undergoes rigorous testing to meet our strict QC standards prior to dispatch.
⏱ Accuracy Profile:
±5–8 s/day. The Shanghai 4130 architecture is highly stable, often outperforming older 7750-based chronograph clones in long-term amplitude consistency.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Hours, minutes, sub-seconds, and fully functional 12-hour chronograph
- ✅ Winding Direction: Bidirectional

Why BT Factory for This Reference?
Many collectors ask: ‘Why not Clean Factory?’
While Clean Factory is renowned for its dial printing precision, BT Factory (BTF) excels in case geometry and crystal transparency. The BTF scratch-proof sapphire crystal sits precisely flush with the bezel, avoiding the milky ring effect that occasionally appears on rival batches. Furthermore, the 12.2mm thickness is achieved with meticulous case back machining.
Full Disclosure: The 18k rose gold plating, while visually prominent, lacks the exact mass of solid Everose gold, resulting in a lighter overall weight (144.5g) compared to the genuine piece.

Collector Q&A
Q: How does the Everose gold plating on the BTF 116505 hold up over time?
A: The 18k rose gold plating applied by BT Factory utilizes a durable PVD process suitable for daily wear. However, it can scratch under heavy impact, revealing the 904L steel underneath. Avoid abrasive surfaces and chemical cleaners to maintain the factory finish.
Q: Is the chronograph fully functional on this Shanghai 4130 movement?
A: Yes. The Shanghai 4130 clone features a true column wheel and vertical clutch, allowing the chronograph to function exactly like the genuine caliber. The sub-dials accurately track running seconds at 6 o’clock, chronograph minutes at 3 o’clock, and chronograph hours at 9 o’clock.
Q: Does the BTF crystal have the etched crown at the 6 o’clock position?
A: Yes, the scratch-proof sapphire crystal features a semi-invisible etched crown (LEC) at the 6 o’clock position. BT Factory is specifically noted by collectors for the subtlety of this etching, which correctly requires magnification and specific lighting to view, unlike the overly visible etchings on lower-tier replicas.
Q: What is the main visual tell on the BT Factory Everose Daytona?
A: The primary tell is the weight. At 144.5g, this 904L steel-based replica is noticeably lighter than the solid 18k Everose gold genuine piece, which weighs over 200g. Additionally, under specific lighting, the rose gold plating may exhibit a slightly different hue compared to Rolex’s proprietary Everose alloy.
