Spent US$5500 so far ! but am thinking about
: going down the NOS/mint route and having two
: or three stunners and one or two every day
: watches.

: Carrera and Autavia are on the list as is an
: Omega Speedmaster, so will see what comes up
: and how much money I have left !

The Speedy Pro is a near perfect watch IMHO. It has the heft of an Autavia and the clean lines of a Carrera.

While they may seem a little common in the watch world, I haven't run across a single one in the real world in the year I've had mine.

While I love the 321s, you might consider an 861 as a daily wearer. The 861s are almost identical to the older watches, and they're so plentiful that they're easily replaced if damaged or stolen, and repair parts are easy to get.

The later bracelets are also nicer and more robust. That said, I love a Speedy on a Strap (mine's on a black Hirsch Professional)
I paid under $900 for mine but that was a crazy deal. You can find a very nice used Speedy for $1500 I would guess.

That's not mine, but nice eye candy nonetheless. (I prefer the less glitzy 80s-90s bracelet.)
