Hey Chef,
I am a huge WIS (watch idiot savant)..
And the first thing you need to know is that top watch you listed is NOT a Big Pilot on buffalo brown strap..
The name of the first watch you posted is called:
The Antoine de Saint Exupery (often called the Saint Exupery.) It is a chronograph, a limited edition and is a 2006 model.
I know this not only because I love that watch, but also because I have the 2007 model which is a non-chrono.
They are supposed to make 3 Antoine De Saint Exupery models (named after the famous pilot/author who wrote, The Little Prince.) ANd the model you have shown is the first of the three. Mine is the second and there will be a new one next year.
The model you have shown is sold out but can be found on the seconday market for at or near the retail price. If I become cash flush anytime soon, I'm going to scoop up the chrono version also.
Just want to note though, because it is on a leather strap, you can't swim with it, or shower, and if you work in an enviorment where you sweat a lot, I would rather see you get a watch with a stainless steel bracelet or at least rubber. I only wear my Saint Exupery if I'm getting dressed up.
