Your clock is an example of the "Marina" series of clocks produced by LeCoultre/JLC circa 1960s. The Marina models were produced in a variety of themes (Fish, Bees, Chinese Motif, Bird of Paradise, Zodiac (yours), etc.) and sizes.
All of the Marina clocks used JLC's caliber 210 inline Baton (aka Baguette) movement.
An example of a couple of other larger Marina models from a 1968 LeCoultre dealer catalog are shown below:
