The Cattin 66 is a quite oddly constructed pin lever movement.
It uses 17 jewels, but two among them are without any function at all and are located on the dial side on top of the mainspring barrel.
The balance jewels are enclosed in a very “special” way: They are surrounded by large plasic frames. Maybe due to the red color, this looks quite nice, but it doesn’t offer any advantages to a metal jewel enclosing. Additionally, due to the lack of a shock protection, it makes the balance axle breaking quicky, if you drop the watch.
The complete gear system is located under one bridge and is not stacked. Since it consumes a lot of space, the cannon pinion must be driven indirectly. This is done like on Roskopf movement by the mainspring barrel, but unlike Roskopf movements, the hour hand is driven by a separate gear.
On the dial side, you also find a yoke winding system - an unusual detail for pin lever movements.
The Cattin 66 was also available in a version with date indication, but under the same name.
