BT Factory Edition — Oyster Bracelet

The reference 116520 represents the pinnacle of pre-ceramic Rolex chronographs, and this BT Factory (BTF) edition captures its nuanced architecture with clinical precision. Recognized among horological enthusiasts for resolving the case thickness discrepancies of earlier replicas, this iteration achieves the correct 12.2mm profile. The integration of the metallic ‘frozen’ textured sub-dials demonstrates a strict adherence to the genuine aesthetic.

At the core of this reference is the Dandong 4130 clone caliber, a vertical clutch chronograph movement that operates with exceptional smoothness. Unlike modified base movements, this dedicated architecture allows for correct sub-dial spacing and pusher feel. Power reserve is rated at approximately 36 hours, ensuring consistent amplitude during daily wear. The mechanism is devoid of superficial decorative plates, focusing entirely on functional replication.

Constructed from solid 904L Oystersteel, the 40mm case features a highly accurate lug profile and a sharp tachymeter bezel filled with black enamel. The white gloss lacquer dial is accented by silver-rimmed sub-dials and applied markers treated with blue Chromalight. The Oyster bracelet is finished with alternating brushed and polished surfaces, culminating in a precisely machined folding clasp.

Why BT Factory for This Reference?

Many collectors ask: “Why not Clean Factory?”

While Clean Factory produces an excellent Daytona, BT Factory (BTF) is often preferred for the 116520 reference due to its superior sapphire crystal clarity and slightly sharper case lug profile. The BTF crystal lacks the milky edge occasionally seen on competing versions, allowing the intricate ‘frozen’ texture of the sub-dials to be viewed without distortion.

Full Disclosure: The raised 3D printing on the dial text is slightly thicker than genuine, which is visible under high magnification.
