Description
On the way, the Otero 437 presents itself, you can clearly see the dark clouds
of the forthcoming quartz age. Instead of allowing open views into the movement,
it is almost hermetically sealed into a container, which protects it from dust and
misusage.
This tiny form movement is pretty impressive, since it even has got an indirect
driven center second hand. The ring balance is secured by a Rufa-Anti-Shock
protection and has got a moveable hairspring stud.
On the dial side, there's a yoke winding mechanism. The setting lever is already
secured by a spring, so for releasing the crown you have to press a button, which
is reachable by the only hole of the container.
