my only watch, the original owner bought it at the airport for 2 week temporary use when he was traveling and didn't want to bring his actual one. He gave it to me before he left. Can't complain about a free watch.
I have a real hard time with this generalization...
If the Longines was something they had just cooked up out of the blue now then fine, however the fact is that both the Polaris and the Legend diver originated in the 60s and from what I have read both companies sourced the cases for these watches (the originals) from the same manufacturer, in fact there were many other companies using virtually the same design.
Both the Polaris and the Legend have a similar yet unique look, not to mention one has an alarm function and costs a ton more money (like 9k for the JLC vs 1,500 for the Longines)
In an ideal world I would love to own the IWC however the frugal side of me doesn't like the look that much and would opt for the savings in the Longines with the ultimate compromise being the IWC vintage collection AquaTimer.
As for Tiffany, my understanding is that now they are made by Swatch and personally I wouldn't care about them unless I was a serious brand whore and just had to have something with the name Tiffany on it, much the same way I feel about vulgari stuff.
