Umm . . .
. . . could you ask an easier question next time?

Seriously, there are countless candidates for my collection. A few no-brainers: the 2014 DeVille Trésor . . .

. . . the 2012 Olympics SM . . .

. . . and its 2012 Speedmaster counterpart, the ref 2998 re-issue . . .
. . . would be on the list of modern releases, but I've decided to wait on the CK2914 re-issue for the modern Omega in my collection.
Any number of vintage models, of course. Any unusual 30 mm Connies, like this Japanese edition . . .

. . . any British military models, like Roger's . . .

. . . Miki's masterpiece . . .

. . . or even a pocket watch . . .

. . . provided it's as special as this.
And please, don't get me started on Omega central tourbillons.
