: So if you happened to own a Porsche 917 or a
: 550 Spyder, and were going to the vintage
: races for a weekend, what would you wear?
: Let's ask for two or three answers: If you
: had to walk into a "modern" watch
: store, selling all the current production
: models, but no vintage or pre-owned, what
: would you select for your vintage racing
: weekend?

Answer #1 - Modern Watch:

A Bell & Ross Tourbillon. Huge, outrageous, stupidly expensive and probably woldn't bump into somebody else wearing one.

: Now, if you had to go to OnTheDash (or let's
: say your favorite Omega or Breitling
: website) and select a vintage chronograph,
: for the weekend, what would it be?

Answer #2 - Vintage Chronograph:

This is not a very creative answer, but I'm going to have to say a Siffert Autavia. Lots of history, great looking watch, very appropropriate for the venue.

: Finally, what if you could select any vintage
: watch, from any source -- Rolex, Patek, etc.
: -- what would you do?

Answer #3 - Blue Sky Scenario:
This is a no brainer. I would hop in my magic time machine, go back to 1969 and beg/borrow/steal a Speedmaster that has actually, verifiably been on the moon. (Pardon the pic of modern Speedy.)
