The Watch

Here we have a 2021 Omega Speedmaster '57 Co-Axial Black 311., inspired by the original Speedmaster from 1957, this modern interpretation takes the best elements of that watch, with a 41.5mm brushed and polished stainless case that sits comfortably on your wrist thanks to the long, straight, flat-ended lugs, and a polished chamfer edge leads to a lug-to-lug length of 50mm and a case thickness of 16mm, giving the watch an impressive wrist presence. Down the right side are polished chronograph pushers and a signed push/pull crown in the centre. A brushed steel fixed bezel has a blackened Tachymeter scale holding a domed sapphire crystal AR coated on both sides for excellent viewing angles. The black dial has an outer minute track precisely executed with applied baton indexes filled with Super-LumiNova marking the hours; at 3 o’clock, we have a recessed 12-hour register; at 6 o’clock, a colour-matched date window and at 9 o’clock, a recessed small seconds register, elegant Alpha hands are filled with the same Super-LumiNova complemented by tapered chronograph hand, at 12 o’clock we have the Omega Speedmaster motif and at 6 o’clock “Co-Axial Chronometer” completes this vintage-inspired Bi-Compax sports chronograph. On the reverse, a screw-down flat sapphire exhibition case back with the details of the watch engraved around its edge, inside an automatic Omega Cal. 9300, features a column-wheel, a silicon balance wheel, and the George Daniels conceived Twin Barrel Co-Axial escapement, 54 jewels, beating at 28800 beats per hour, designed for better durability, precision and stability, decorated in an attractive swirling Côtes de Genève. The watch comes paired with its 20mm Omega brushed and polished stainless steel bracelet secured by a signed concealed push button release butterfly clasp; all links are provided, and the watch comes with its Omega presentation box and paperwork.

Personal Note

This is the now discontinued Omega Speedmaster '57 featuring the automatic Co-Axial calibre 9300 through a case-wide exhibition back which is mesmerising to look at and appreciate. At 41.5mm the case is more than wearable and looks impressive on the wrist, do keep in mind this is thicker than your standard Speedy Professional due to the automatic movement, so do not hesitate to book an appointment and try it on for yourself if you are unsure!

The Brand

Formerly known as the La Generale Watch Co. in 1848, it was founded by Louis Brandt in La Chaux-de-Fonds. When he died in 1879, his sons carried on his dream. In 1880, they moved to 96 Rue Jakob-Stampfli, where they remain today. The brothers produced their first mass-produced calibre, the Labrador In 1885. Just a few years later, in 1892, they produced the first minute-repeater. In 1903, they renamed the company Omega until 1982, when they officially changed their name to Omega SA. During WW1, Omega watches were used as official timekeepers for the Royal Flying Corps and the US Army. In 1930, Omega and Tissot merged together to form Société Suisse pour l'Industrie Horlogère (SSIH). In 1931, another group was formed - Allgemeine Schweizerische Uhrenindustrie AG (ASUAG). Where SSIH was primarily French-speaking, ASUAG was founded by the more German-speaking members of the Swiss watch industry. In 1948, they introduced the first edition of one of its most symbolic watches: the Seamaster. Omega first introduced the Constellation in 1952. At the time, it was Omega's flagship timepiece. The first models had a Cal. 354 bumper movement in them. Later, in 1955, Omega introduced the Automatic Cal. 50x, followed in 1959 by the Cal.55x (no date) and 56x (date) versions. Many of the Constellations came with pie-pan dials, diamond indexes, and fancy lug configurations. All the gold Constellations of that time have the Observatory of Geneva's hand engraved on the back. The stainless steel and stainless steel/gold versions had a gold medallion on the back with the Observatory of Geneva. The eight stars above the Observatory stand for the many exploits of Omega in the world Chronometer competition. Celebrating the fact that all Constellations are Chronometer Certified. In 1962, when astronaut Wally Schirra wore a Speedmaster on his Mercury Sigma 7 Mission, making it the first Omega watch to enter space. After rigorous tests, NASA used Omega for all their Apollo missions, including the 1969 Moon landing of Apollo 11. Today, Omega is still the first choice of astronauts. In 1969, President Nixon famously said it was “too valuable” and turned down the first-ever all-gold Speedmaster Professional Deluxe. As a response to the ever-growing threat of electronic watches to the manufacturers of mechanical watches, Omega and many Swiss brands such as Rolex and Patek Philippe formed Centre Electronique Horologer (CEH). Prototypes began to appear in 1967, and their production started in 1968. Then, In 1972, Omega introduced the reference 198.030, which included the Omega calibre 1250, a ‘tuning-fork electronic movement which was made under licence from Bulova. Later we saw a merger of SSIH and ASUAG into SMH, or Société de Microélectronique et d’Horlogerie. This merger took place in 1983. In 1992, the company acquired Blancpain, and in 1998, it officially branded itself from SMH to the Swatch Group. Then, in 1999, they purchased and integrated Breguet into the Swatch Group.
