This is a mid-1960's watch. The illustrious Chuck Maddox would know the details of the details. I do have this watch on a perforated black strap right now, but I'm about to put it on the bracelet. I've got to wear that bracelet!
Some things I know about why this watch made such an impression and continues to do so:
Certainly the re-edition of a decade or so ago introduced this design to a new generation. That re-ed. has a Lemania inside--it's a collector's item in its own right, and an amazing value.
The case design, in the 1960's, was thrillingly original. The lugs are Carrera lugs--no other case that I know of has such lugs. It was very modern.
The watch's birth was in racing history, and 'boys' love racing cars and chronographs together to this day.
It has the famed Valjoux 72 inside, which is widely acknowledged as one of the all time great manual wind chrono movements.
And I'll say this, too. The engagement of the chrono function, the feel of the pushers is up there with watches 10 times the price. It amazes me every time I use the chrono.
Then, add in the fact that it's a 'real' chrono with three subdials giving you a chance to time real events--not only 30 minute'ers...
But maybe most of all, I beleieve it comes down to purist design. Design following function. This dial is truly legible, and the subdials are too. It just makes sense. Every element is harmonious, and minimal, it has a kind of perfection, but of course I feel that way!
Thanks for kind words.
