Tissot Caliber C01.211-710 Pallet Fork

Product Description

This is an OEM‑specification pallet fork for the Tissot Caliber C01.211 automatic chronograph movement, part number T245039259. Developed by ETA in 2008 for Tissot, the C01.211 movement is based on the legendary Lemania 5100 design, featuring a 13.75‴ (31mm) diameter and 8.44mm height, operating at 21,600 vph. To control costs and adapt to modern production, the escapement of this movement is manufactured from high‑performance synthetic materials. This pallet fork, which has no traditional ruby pallet stones, is a key component of that design. Working with the similarly constructed escape wheel, it converts gear train energy into precise oscillating pulses, controlling timekeeping accuracy.

When the original pallet fork becomes worn, deformed, or broken — causing the movement to stop, lose accuracy, or exhibit low amplitude — replacing it with this OEM‑spec part is an effective solution to restore proper movement function.

Key Features & Function

• OEM‑Specification Replacement – Designed specifically for the Tissot C01.211 chronograph movement, with dimensions and geometry matching factory standards for a perfect fit.

• Escapement Core – Works with the escape wheel to convert gear train energy into escapement pulses, directly controlling timekeeping stability and accuracy.

• High‑Performance Synthetic Material – Manufactured to OEM specifications using high‑performance synthetic material, with no traditional ruby pallet stones, fully consistent with the movement‘s design language for efficient escapement operation.

• Optimized for the C01.211 – The friction characteristics of this hybrid escapement differ from all‑metal designs; this part perfectly matches the movement’s escapement geometry.

• Essential for Service – When the pallet fork becomes worn or damaged, causing movement failure, replacing it is the preferred solution to restore full function.

Applications 

• Tissot Caliber C01.211 automatic chronograph movement (found in Tissot Couturier, PRC 200, T-Race, Seastar 1000, Carson Chronograph, etc.).

• Repair of movement stoppage, severe timekeeping errors, very low amplitude, or unusual escapement noises.

• Replacement of pallet forks with worn, deformed, or broken pallet arms to restore escapement efficiency and timekeeping accuracy.

• Replacement of pallet forks found worn or damaged during routine service.

Frequently Asked Questions

1. Is this a genuine Tissot/ETA pallet fork?

This is a high‑quality OEM‑specification replacement part, not an official factory original, but its dimensions, geometry, and material are manufactured strictly to C01.211 movement standards for direct replacement.

2. What is special about the C01.211 pallet fork?

To control costs, the C01.211 movement uses a high‑performance synthetic pallet fork together with a synthetic escape wheel, with no traditional ruby pallet stones. The friction characteristics of this design differ from all‑metal escapements, requiring special care during servicing and lubrication.

3. What are the symptoms of a damaged pallet fork?

Typical symptoms include: the movement stops completely or runs intermittently; greatly increased timekeeping error; very low amplitude (typically below 200 degrees); irregular or abnormal ticking noise from the escapement; chronograph function abnormal.
