The Rolex Calibre 1065 was produced around 1965, and was a robust and well engineered movement featuring a free sprung balance and bi-directional automatic module. A minor complaint is the lack of a quick date set function. This particular movement in for service was in great condition…no corrosion or excessive wear.
Debris mixed with coagulated oil
