Today's offering showcases this uncommon automatic Speedmaster, ref. 3511.80. The case and bracelet both carry a traditional speedy look, although the bezel is of the sleeker steel embossed variety. Note that all of the black is fully intact and strong in the numbers on the bezel (a few of our photos make it look like it isn't.) The black and silver so-called Panda dial give it a nice look. And the luminous is beautifully toned. It is fully original and in beautiful condition - it presents as a 9.4 or 9.5 out of 10. Our Master Watchmaker has fully serviced the watch which consists of fully disassembling the movement, carefully inspecting each part, replacing any overly worn components, reassembling and lubricating the movement, replacing all of the seals, and extensive timing testing and regulation (a $595 value). It continues to keep time virtually on par with a new Speedy, maintaining chronometer grade accuracy in three testing positions.

When Neil Armstrong took his first step onto the moon proclaiming, "This is one small step for man, one giant leap for mankind," he leapt with the first and only timepiece to land on the moon, Omega.

In La Chaux-de-Fonds, Switzerland 1848, Louis Brandt founded Omega with the foundation of providing innovative and well-crafted timepieces. Now, Omega stands as the official timekeeper of 21 Olympic Games and the official chronometer for NASA.

Omega has been adored by many leading public figures including President John F. Kennedy and Prince William. The Omega brand has also been sponsored by celebrities and athletes such as George Clooney, Daniel Craig, Nicole Kidman, and Michael Phelps.
