Eppler 6

Description

In the 1960s, the german manufactury Eppler launched their series of 10 1/2 ligne pin lever movements, which was especially popular in the 1970s, when they were used for many, many character watches under the brand name “Anker 100”.

The caliber Eppler 6, which could only display hours and minutes and, if wanted, decentral seconds, was the base caliber.

It differs from its successor, the caliber series Eppler 16 by still using a fixed hairspring stud.

As common on pin lever movements, the Eppler 6 uses no ruby bearings, too.

The gear train is typical and classical for this kind of movement: Mainspring barrel, center minute wheel, third wheel, decentral seconds wheel at position “6” and the escape wheel.

The two-leg anular balance has got no dedicate shock protecton and beats slowly with 18000 A/h, which could be more or less adjusted on the simple, just u-shaped hairspring key.

Since only a pointed staff is used, there’s no need for a further shock protection. This also explains, why this virtually undestroyable movement was often installed in character watches for children in the 1960s and 1970s.

Apart from the rocking bar winding system and the well executed ratchet, you see a “screw” at position 9 o’clock. This is the dial side pointed staff bearing for the balance wheel, of which the height play can be adjusted here.

In the lab

The movement came heavily used into the archiv, got a simple revision, but was afterwards still not able to perform well on the timegrapher.
