The Femga 67 is a typical representative of the many, many 5 1⁄2 ligne ladies’ watch movements of the sixties.
In terms of construction, it is a little bit unusual though, because on the one hand, it contains modern technology like a semi-fast, with 21600 A/h beating balance with three legs, on the other hand, it contains old fashioned details like a hairspring, which is fix connected to the balance cock.
A detail, which is not often found on these movement is the ruby-beared minute gear. Usually, the seventeeth jewel is made as cap jewel for the escapement wheel, but here, it bears the minute gear on the dial side. Technically, there’s no real need for this, because the power from the mainspring is still much too strong for any bearing issues.
On the dial side, you see the yoke winding system as well as the shock protection.
