ZIM 2608


The ZIM 2608 is a quite old and unusual handwinding movement of russian production, which was equipped with and direct center second and therefor builds really high.

Additionally, the specimen shown here has got a very nice stripes decoration on the plates, while elsewhere it looks pretty crude.

The caliber 2608 bases on the construction of the familiy relative ZIM 2602. For the direct driven center second, the fourth wheel was removed from position “6” and the third wheel was set further distant from the center.

Since fourth and third wheel are now located above the winding plate, the escapement wheel train had to be prolonged, which all leads to a very high building movement.

Like the ZIM 2602, this movement also uses a three leg ring balance with a Breguet hairspring. The balance is not yet shock protected and the hairspring key doesn’t have a long regulator arm. So, this movement was build cheap and expensive the same instance.

Pretty funny: The “watchmaker”, who put hands last on this movement, managed to set the hairspring key wrongly, without any function, onto the balance cock.
