"The Movado Super Sub-Sea & Zenith reference A277, were both manufactured at late the 1960s when the two brands worked closely together. As a result this Movado houses a chronograph movement from Zenith, the caliber 146 HP from a Martel ebauche. It comes with a large compressor case whose water resistance justifies the Super Sub-Sea reference name. Its sheer 41 mm size makes it quite wearable on the wrist, while the reverse panda dial and the external bezel are very legible."
