Judging by your post, I would say, go for the Explorer, even though Im not a fan of the watch.
Personally, I prefer the other two,JLC is a great dress watch, and the tri color Zenith is another superb watch. Both are on my 'hit list'. But when it comes to watches, the heart wants what the heart wants. Its not about price, movement etc.
Since youve always wanted an Explorer, go for it. Chances are you wont regret it.
