Product Description

The Rolex 3135-301 click spring is a precision elastic component within the automatic winding module of the Caliber 3135 and its derivatives (e.g., 3130, 3131, 3185, 3186), referenced as part number 301. Its core function is to work in unison with the click to unidirectionally lock the ratchet wheel during automatic winding. This ensures that the bidirectional winding torque from the oscillating weight is effectively transmitted and stored in the mainspring, while also preventing the wound spring from unwinding due to shocks or vibrations – a critical guarantee for winding efficiency and timekeeping stability.

Compatible Movements: Caliber 3135 (Rolex’s main production automatic movement from 1988 to 2020) and its platform‑derived calibers, including 3130 (no‑date), 3131 (anti‑magnetic), 3185/3186 (GMT), 3155 (Day‑Date), and the entire 31XX family.

Core Function: Works in conjunction with the click to form a unidirectional locking mechanism. During automatic or manual winding, it allows the ratchet wheel to rotate in one direction to tension the mainspring. When winding stops or a reverse torque is applied, the click spring presses the click into the ratchet wheel‘s teeth, instantly locking it and preventing the spring from unwinding.

Part Characteristics: A micro‑sized stainless steel wire spring, precision heat‑treated and formed with a specific spring force curve. Installation requires a thin spacer located underneath it to regulate the operating height and pre‑load.

Repair Value: When the click spring weakens, deforms, or breaks due to metal fatigue, the movement may exhibit symptoms such as a “slipping” sound during winding, reduced automatic winding efficiency, or irregular free‑play during manual winding (commonly known as “stripped clicking”), necessitating replacement with this genuine part.

FAQ

Q1: How do I know if the click spring needs replacement?
A: If you feel a distinct “slipping” or “jumping” sensation accompanied by a clicking noise when manually winding, or if when servicing the movement, the click feels weak and does not snap back properly, the click spring should be replaced immediately.

Q2: Are there any tricks to prevent the click spring from flying away during installation?
A: Always cover the spring with a piece of Rodico putty before attempting to remove or install it. This dramatically reduces the chance of it flying away. Also, demagnetize both the spring and your tweezers before handling, as magnetism can also cause them to slip.

Q3: Can a failed click spring cause complete automatic winding failure?
A: Yes. A failed click spring (e.g., broken or severely deformed) will prevent the click from locking the ratchet wheel, causing the power from the rotor to be released backward. This can drastically reduce or even completely stop automatic winding. However, note that complete automatic winding failure can also be caused by a clogged or worn reversing wheel; thorough diagnosis is required during repair.

Q4: What if I lose the spacer under the click spring?
A: This spacer is a precision component and cannot be replaced with a generic part, as it affects the exact pre‑load of the spring. The only proper solution is to order the genuine Rolex spacer (part number likely 3135-307 or similar) from Rolex or an authorized parts distributor.
