There are legendary Black Memovox everybody knows, such as the Polaris and the Deep Sea Alarm of course.
But there are also some strong contenders, such as this Memovox E 855 Black, which doesn't lack charm nor appeal:
Finding one, an all correct one, is not such an easy game. Even less in good condition.
This one is a jewel, with its deep glossy black gilt dial.
Made in the late 60's for a few years. 37 mm steel case. Cal 825 automatic alarm movement.
Enjoy,
Nicolas
