Description
When Ronda movements with pallet lever movements were still marked with “RL” instead of “RAX”, this movement was made. Despite the “Antichoc” marking on the dial, it does not use a balance shock protection, but the balance uses plastic bearings! For reaching the magic number of seventeen jewels, it uses lots of deck jewels, at least one of them sealed in a kind of chaton.
For quick releasing of the mainspring, it uses a seperate bearing, which can be released easily.
