Description

The Amida 710, which was probably launched in the early 1970ies, is a modern decorated movement with a completely frosted finish, which could have been launched in the 1980 as well.

Its construction is like on Roskopf movements: On the movement side, there's no direct connection to the hands works, which is here driven from the mainspring barrel.

The three-leg (modern shape) ring balance is beared in two Incabloc shock protection systems and beats slowly with 18000 A/h.

The hairspring is connected to a moveable stud and can be regulated in its effective length on the hairspring key only.

The construction of this pillar movement is remarkable, since it's only one-storied, which results in a very flat (only 3.8mm in height) building, being perfectly suitable for elegant waches.

Even a center second indication would be possible - on the plates, there are already the preparations for the bushings - on the movement side, there's even a jewel, which is currently unused.

On the dial side, which looks like being made by a robot, you see the yoke winding system.

Unlike true Roskopf movements, the Amida 710 is a bit special: The hands are not directly driven by the mainspring barrel, but the mainspring barrel drives the changing wheel, which consists of two concentric gears with a friction coupling. The lower wheel is connected with the mainspring barrel, the upper wheel with the cannon pinion and the hour wheel.
