In Geneva this weekend, Antiquorum is offering the chance to bag one of the biggest prizes in watch hoarding: the famed Omega Speedmaster Missions Collection.

The limited-edition set, of which only 50 were ever produced as a tribute to Omega’s legendary Speedmaster Professional (as worn by Buzz Aldrin), which celebrated its 40th anniversary in 1997, is expected to fetch up to $100,000 or so.

And now we’ll tell you why it’s worth it.

The set contains a special series of 23 Speedmaster watches presented in a case covered with genuine spacesuit cloth.

Each of the first 22 watches wears a different official NASA mission patch on its dial at 9 o’clock, from the August 1965 Gemini V to the November 1973 Skylab SL-4.

The collection also includes a replica of the original 1957 Speedmaster.

You may never make it to the moon, but this might just be the next best thing…
