Buzz Aldrin during Apollo 11 Significant dates in history are often worth revisiting.
Such is the case, this weekend, as we celebrate the anniversary of the
first human beings ever to step foot on the moon's surface. Indeed, July 21 marks the 45th anniversary of the famed moon walk. On July 20, 1969, the USA landed its Apollo 11 lunar module, called Eagle, on the moon's surface in the Sea of Tranquility.
Two NASA astronauts became the first to ever step foot on the moon the
very next day – one of mankind's crowning technological achievements. 
The first humans on the moon were Neil Armstrong and Buzz Aldrin.
Armstrong was the first to step onto the lunar surface, describing the
event as “one small step for man, one giant leap for mankind.” He and
Aldrin spent a couple of hours outside the spacecraft setting up
equipment and collecting lunar material.
The third astronaut, Michael Collins, piloted the command spacecraft
alone in orbit until Armstrong and Aldrin returned less than 24 hours
later for the trip back to Earth. This conquest effectively ended the international space race. 
Omega Speedmaster Professional Apollo 11 45th Anniversary Limited Edition watch Time played a critical role in the space program, and so did timepieces.
The leading role in the NASA space flights and the walk on the moon was
played by Omega, as it was the official watch of NASA, having undergone
rigorous testing over the course of many months. The astronauts on the Apollo 11 mission were equipped with Omega Speedmaster watches.

Today, as we celebrate the 45th anniversary of the momentous event,
Omega releases a new Speedmaster Professional Apollo 11 45th Anniversary
Limited Edition watch. Just 1,969 pieces will be produced. The brand also offers its much-sought-after Omega Dark Side of the Moon watch.
The all-black, all-ceramic (case, dial, buckle, pushers) Omega Co-Axial
Speedmaster salutes the pioneering spirit and pays homage to the
Speedmaster Professional chronographs worn by Apollo astronauts. The watch is the first industrially produced timepiece made entirely from one block of black zirconium oxide ceramic via a host of processes that include diamond-wheel brushing, aluminia polishing, stage heating, laser etching and more. What's really cool about the dial – something you barely even notice at first glance – is that very discreetly in the center lie the letters: Zr02. Translation: Zirconium Oxide – just to let everyone know that the dial is ceramic, too – something very few others in the watch world can achieve.
