== Manual-wind Oyster Precision (1939–1948) ==

Manual-wind Oyster Precision references ran in parallel with the automatic Bubbleback through the 1940s. The cases are tonneau or cushion Oysters with the same hermetic screw-back architecture; the difference is the movement, a Hunter-derived manual instead of the Cal. 520 / 620 / 630 rotor automatics that defined the Bubbleback line.
