This is a genuine second wheel designed for the Rolex Caliber 3135 self-winding movement, part number 3135-360. As a key component of the movement’s gear train, the second wheel transmits power from the third wheel to the escapement system and drives the center seconds hand. As an original factory part, it is the ideal replacement for worn components during service or repair.
Genuine Rolex Part – Manufactured by Rolex, not a copy or generic component; highest quality.
Compatible Movement – Designed for Rolex Caliber 3135 automatic (also fits some 3135‑based calibers like 3136 with verification).
Core Transmission Component – Positioned between the third wheel and escapement; also drives the center seconds hand. Tooth profile precision directly affects timekeeping stability.
Brand New – Unused factory‑original stock, no wear or deformation.
Direct Replacement – Exact fit for the original movement without modification.

1. Is this a genuine Rolex second wheel?
Yes. The product is clearly a factory Rolex part (Caliber 3135-360), not a third‑party copy.
2. Which movements does this second wheel fit?
Primarily Rolex Caliber 3135. It may also fit related calibers like 3136 (used in Datejust II), but check the official parts catalog. Not compatible with 3130 (no‑date) or other non‑3135 based movements.
3. How can I tell if the second wheel needs replacement?
Symptoms include: jerky, trembling, or stopping seconds hand; significant loss of accuracy; or visible tooth wear / bent pivot during service. Professional inspection during a full movement overhaul is recommended.
4. What should I pay attention to during installation?
The second wheel sits between the third wheel and escape wheel. Ensure both pivots align with their jewel holes and that the teeth mesh properly. Follow the Rolex technical guide and apply a tiny amount of appropriate lubricant. Professional installation is strongly advised.
5. Why is this part so expensive?
Rolex genuine parts use top‑tier materials and ultra‑high precision manufacturing. Brand premium and scarcity drive the price well above generic parts, but they guarantee perfect fit and long‑term reliability.
