More about Omega:

Launched in 1957 as a sport and racing chronograph, the Omega Speedmaster has become one of the most well-known chronograph models ever. The first Speedmaster model was the reference 2915, featuring a distinctive luminous broad-arrow shaped hour hand. It was outfitted with the caliber 321, which would be used until 1968, when it was replaced by the caliber 861.

Starting in 1962, NASA began testing a series of chronograph watches from various brands (including Breitling, Longines, Rolex, and Omega) for their astronauts to wear to space. Only three watches passed the first round of “Qualification Test Procedures” and went on to final stages of testing. Omega’s Speedmaster chronograph was the only model to pass final testing, and went on to space. Following this event, Omega added the word “Professional” to the dials of their Speedmaster models, and gave them a new reference number – 145.012.

This rich history behind the Omega Speedmaster is one of the many reasons why the model has developed an almost cult-like following in the collectors and enthusiasts community. The popular hashtag, #SpeedyTuesday, coined in 2012 by Fratello Watches editor Robert-Jan Broer, is, today, almost omnipresent on social media every Tuesday.  This “Speedy Tuesday” example was produced in a limited edition of 2012 watches to commemorate the beginning of the hashtag and based on the “Alaska Project III” Speedmaster favored by collectors.
