Omega's annual calendars are my favorites, too . . .
. . . and I came close to acquiring a SM Aqua Terra when it was introduced a dozen years ago.

I would've gone for the two-tone red gold / steel version on a strap. As it happens my attention was drawn elsewhere so the Annual never entered my collection. As a retiree now the last complication I need is a perpetual (or annual) calendar so my interests have changed accordingly. But if a compact AT Annual popped up at a local boutique I'd still be sorely tempted.
