The 420kt Caliber Watch Movement by Cymas, specifically the Tavannes version, is a masterpiece of horological engineering that combines precision, durability, and style. This automatic movement, identified by its model number 420kt, is a testament to Cymas' dedication to crafting high-quality timepieces.
The Tavannes caliber is known for its robustness and reliability, making it an ideal choice for watch enthusiasts who appreciate both function and form. The movement houses a 25-jewel system, which minimizes friction and ensures smooth operation of the watch's mechanical components. This results in an accurate timekeeping, with a power reserve of around 42 hours when fully wound.
One of the standout features of the 420kt Caliber Watch Movement is its bumper automatic winding system. This mechanism uses the natural movements of the wearer's wrist to wind the watch, ensuring a constant supply of power. The bumper system is particularly effective in situations where the wearer's wrist is not moving continuously, such as during sleep.
The 420kt Caliber Movement is also renowned for its shock resistance, thanks to its Incabloc shock protection system. This system, developed by Swiss watchmaker Georges Piguet, uses a series of small rubber or plastic balls to absorb and dissipate the impact of any shocks, protecting the delicate mechanical components within the watch.
In terms of aesthetics, the 420kt Caliber Movement features a finely decorated rotor, adding a touch of elegance to the watch's inner workings. The movement is often finished with Cymas' signature blue screws, which not only add a pop of color but also serve to secure the movement's components.
In conclusion, the 420kt Caliber Watch Movement by Cymas, Tavannes version, is a perfect blend of functionality and style. Its robust construction, reliable operation, and unique bumper automatic winding system make it a must-have for any serious watch collector.

I can not tell if it is good or not. It is not in working condition. It may be broken or this is a sweep second hand movement.
I can not find the caliber on the movement but looks to be 420 or 420KT. The rotor moves freely. The hour wheel is missing. The balance jewel on the dial side is missing so the balance is wobbly.
The mainspring is wound tight. The movement is dirty and parts will need to be cleaned. This is a Cyma Tavannes watch bumper movement.
This movement is for parts or to repair. I do not feel a pivot on the dial side for a sub seconds hand.
