Omega is one of the world’s most recognizable luxury watch brands.  Although founded in 1848, the company did not become known as Omega until 1894, when the company took the name of its highly successful new watch movement.  The revolutionary movement used a single crown for both winding and time setting.  Success followed success when in 1905, due to its commitment to accuracy, Omega became the official timekeeper for Swiss sporting events.  Later in 1932, Omega became the official timekeeper of the Olympic Games.  To mark Omega’s 100th year anniversary, Omega introduced the watch that would become one of the world’s most popular watches, the Seamaster.  While these are remarkable achievements, the watch that made Omega a legend among watchmakers was the Speedmaster, the only watch to survive the brutal NASA testing requirements and the only watch certified by NASA for use in Space.  It is no surprise that Omega watches are recognized today as spectacularly rugged tool watches hiding in a luxury watch.
