Would have to be the Monaco 50th anniversary alongside the Omega moon landing anniversary.

Quite sure every watch enthusiast is eagerly awaiting the anniversary releases of these two icons but as in the case these days so will the speculators. Could Tag go for an exact copy of the original with rounded chrono pushers etc and with Omega, God only knows what they will produce and in what form of limited edition numbers.

If you were after an Anniversary model, could you get any better than the Moonlanding!
