Product Description

This is a genuine Swiss-made Blancpain original sliding pinion (also referred to as clutch pinion or sliding clutch pinion) for the Caliber 1315 automatic movement – a key component of the keyless works and clutch module. Launched in‑house by Blancpain in 2007, the Caliber 1315 is the powerhouse behind the brand‘s flagship Fifty Fathoms and Bathyscaphe collections. The movement contains 227 components, 35 jewels, and measures just 5.65mm in thickness.

To withstand the extreme conditions of deep‑sea exploration, Blancpain engineers pioneered a robust sliding pinion within the keyless works – a precision steel component that seamlessly engages and disengages the crown’s power path when switching between winding and hand‑setting positions, protecting the delicate gear train (Secured movement).

It also transmits torque when independently advancing the date display via the quick‑set mechanism. When the original sliding pinion suffers tooth wear, a broken pivot, or produces abnormal noises when pulling the crown, this OEM part is the definitive solution to restore quick‑set function and keyless works integrity.

Features & Function

Genuine Quality: Factory‑produced by Blancpain Switzerland, brand new. As one of the brand‘s most strictly controlled calibers, the sliding pinion is manufactured at La Chaux‑de‑Fonds by François Golay, ensuring perfect compatibility with the original movement design.

Compatible Movement: Blancpain Caliber 1315 automatic (35 jewels, 227 components, 4Hz / 28,800 vph, 5‑day power reserve, 5.65mm thickness).

Position in Keyless Works: The sliding pinion is mounted directly on the winding stem and slides axially. When shifted by the yoke lever, its internal teeth or beveled end teeth engage or disengage with the clutch wheel and winding pinion, determining whether crown rotation winds the mainspring or advances the hands.

Contribution to Quick‑Set Date: When the crown is pulled to the first position, the sliding pinion transfers rotational torque through the intermediate wheel train to the date driving mechanism – each full turn advances the date disc by one day without affecting the hour/minute hand position.

Synergy with Triple‑Barrel System: The three barrels that deliver the 120‑hour power reserve operate under minimal friction. Any additional drag from a poorly meshed sliding pinion would reduce efficiency. Therefore, this pinion is manufactured with a specialized surface‑hardening process, and its beveled engagement surfaces are polished.

Repair Value: A worn or damaged sliding pinion will cause the following symptoms: ① vague detent feel when pulling the crown (no crisp positional click); ② the crown cannot hold its position in a given setting; ③ date quick‑set feels stiff or jams; ④ periodic grinding or slipping when manually winding. When any of these occurs, the sliding pinion must be replaced. It is one of the shortest‑lived components in the keyless works due to frequent beveled tooth engagement and wear.

Maintenance Advisory: When replacing the sliding pinion, always inspect the mating yoke, clutch wheel, and winding pinion for corresponding wear. In the Caliber 1315, these parts develop matching wear patterns – for scientific renovation, replace the entire keyless works assembly as a set.

FAQ

Q1: What is Blancpain’s “Secured movement” feature, and how does it relate to the sliding pinion?
A: The Secured movement is an integrated protection system within the caliber that prevents accidental damage to the gear train when the crown is in the wrong position. The sliding pinion‘s specially designed end teeth are the actuation core of this system.

Q2: Should the sliding pinion, clutch wheel, and yoke be replaced together as a set?
A: Yes, professional practice strongly recommends replacing all three together. Their wear surfaces are interdependent; replacing only one will soon lead to rapid wear of the new part. Replacing as a set ensures proper engagement and extends long‑term stability.

Q3: How can I avoid damaging the sliding pinion‘s end teeth when using the quick‑set date?
A: Simply follow Blancpain’s operating guidelines: never adjust the date between 21:00 and 03:00. If the crown feels stiff when turning in the quick‑set position, stop immediately – continuing will overload the end teeth and cause fracture.

Q4: The end teeth of my sliding pinion look fine to the naked eye. Is replacement necessary?
A: Yes. Failure often begins at the micro‑level. Under 20x magnification, a polished wear band on the end teeth indicates metal fatigue. Even if not visibly broken, it has lost its original hardness and will soon accelerate wear on mating parts – proactive replacement is strongly recommended.

Q5: Is the Caliber 1315 sliding pinion interchangeable with IWC or Omega keyless works parts?
A: Absolutely not. The tooth module, bevel angle, bore diameter, and shoulder height are different for each brand. Even if they appear similar, installing a non‑Blancpain part will cause complete jamming or lack of engagement. Use only the genuine Blancpain original part.
