The A. Schild 1706 is an interesting movement with a somewhat unusual automatic winding mechanism. As we shall see in this article, this design has some benefits, but one major potential pitfall.

Kicking off a new blog series, we take a look at the Gruen N 710 SS. This 1960s automatic movement was manufactured for Gruen by… someone. It’s a bit of a mystery, as, beyond a stamp indicating Swiss manufacture, the movement only has Gruen markings.
