When the Sub Sea 1000m entered production, Zenith was already producing seven other dive watches, ranging from the 50m A3634 to the mighty Defy Diver A3648, which Zenith has recently re-released in a modernised guise. The Sub Sea 1000 we have here is certainly the most obscure. Four variations were produced, black, blue, yellow, and this, the only bi-colour option: black and orange.
