The Fleurier caliber 400 is a classic ladies’ watch caliber of the mid of last century. From its construction it is similar to an ETA 1301, with its large height due to the directly driven center second and the required two-storeyed construction.
The axle of the anchor wheel, which runs in two bearings with cap jewels, is very high and not easy to handle on servicing works.
The FEF 400 uses a total of three cap jewels which leads to the “magical” number of seventeen jewels. Two of them, the two anchor pallets, are uncolored.
