Omega Speedmaster Professional Review
The Omega Speedmaster Professional watch is a
significant and historical timepiece, especially
in the aviation and aerospace industry, and is
one of the most trusted watches today for pilots
and astronauts alike. This watch has been on
numerous flights both around Earth and into
space, most famously on the Gemini and the Apollo
space missions.

History of the Omega Speedmaster
From its original conception in 1957 until today,
the Omega Professional has hardly changed over
the years. It is still as elegant and as reliable
as ever, though a few minor tweaks have been made
as technology has gotten better. This watch
features a stunning 42mm stainless steel case,
and a hand-wound movement that can only be
described as infallible. In fact, the only thing
that has changed throughout the years is the
calibre that drives this timepiece. 
The first watches were powered by a calibre 321,
which soon changed in 1968 to the calibre 861.
From there, OMEGA introduced a rhodium plating on
the movement, which allowed for a longer lasting,
and ultimately more efficient watch movement,
which soon resulted in the calibre 1861 and 1863.
Despite these changes, the Omega professional
moonwatch has maintained the same accuracy and
readability throughout the years, and has
remained largely unchanged from the first time it
was featured on the moon.

The Omega Professional Watch in Space
In 1970, Jack Swigert, an astronaut on the Apollo
13 flight, used the Omega Speedmaster
Professional to accurately time the mid-course
correction of the crafts propulsion module after
a ruptured oxygen tank put the craft in jeopardy.
The prompt response of Mr. Swigert, coupled with
the accurate time-keeping of the Omega
Speedmaster is the reason that the Apollo 13 crew
made it back to Earth safely. Because of this
flight, NASA awarded the Omega Speedmaster - and
the crew of the Apollo 13 - with the Snoopy
Award, a highly prestigious award signifying an
outstanding achievement related to human flight
and mission success.
