Non diving versus diving. Ok, the size is not the same, the case either, but the dials are very close, even if different in several points. E 855 Black from circa 1967: E 859, Lecoultre Polaris 1965. The indexes on the E 855 are more bent, the alarms dots...
Interesting to see how two watches that have a sort of similar look can have such different character. Nice duo, I like both although I prefer the Polaris. Cheers
