The Speedmaster Professional is worn by astronauts in outer space. When NASA chose this watch, they requested a hesalite crystal, which "unlike a sapphire crystal" does not break into tiny fragments on impact.This feature is very important for astronauts, as the tiny fragments of a broken sapphire crystal would pose a danger in a zero-gravity environment. The Speedmaster Professional with reference number 3570.50.00 is the original Moon Watch. This model is made of stainless steel on a stainless steel bracelet, fitted with a black dial and a hesalite crystal. It is waterproof to 30 metres/100 feet and is equipped with the calibre 1861 manual-winding movement. As the only chronograph to be flight-qualified by NASA for manned space missions, it is the only watch ever to have been worn on the Moon. Today, over 30 years later, the Speedmaster remains a legend in watchmaking, its popularity unwavering amongst aficionados of classic timepieces. The Speedmaster Professional was first flight tested in space by Walter Schirra aboard Sigma 7, October 1962. The Omega ran flawlessly and was used as backup to the on-board clock. On-board timing devices in the Mercury capsule were internal to the spacecraft and wristwatches had not undergone rigorous testing, as the astronaut never left the protected environment of the spacecraft. On the last Mercury Mission, Gordon Cooper wore both the Omega chronograph and a Bulova Accutron Astronaut in order to compare the accuracy of the manually-wound Omega to the then new electronic Bulova. The Omega Speedmaster Professional is a classic Swiss chronograph with a cult-like following. It and its predecessors have been in continuous production for over 40 years. This current model is in a 42 x 14.5mm SS screw back case with "The first watch worn on the Moon" inscription on the screw back, water resistant to 30 meters. It is on a signed SS bracelet, the latest version with release buttons on the deployant clasp, long enough for an eight inch wrist. This Omega Speedmaster Professional watch is in near mint condition, without a scratch or other imperfection of the case, bezel, dial, or the acrylic crystal, only very minor scuffs on the bracelet and a pinpoint ding on the back edge of the lug at one. The Omega cal 1861 18 jewel manual winding movement maintains accurate time within a tolerance of six seconds per day, and the chronograph functions precisely.

This Omega Speedmaster 50th Anniversary watch in stainless steel features a black dial with luminous hands and index markers, chronograph counters, and a black tachymeter bezel, in a 42 mm case on a steel link bracelet. The Omega Speedmaster 50th Anniversary watch also features a COSC certified Co-Axial manual wind movement with a chronograph function and is water resistant to 100 meters. This Omega Speedmaster 50th Anniversary watch is a limited series.

The Speedmaster "Broad Arrow" takes its name from the shape of its hands. The striking arrowhead hour hand was used on the first Speedmaster and has since enjoyed renewed popularity with the recent Speedmaster models. Other unmistakable OMEGA traits, such as the ivory dial with applied blued hour markers and blued steel hands, confer the legendary Speedmaster design ethos upon the new "Broad Arrow". The models with a stainless steel case are available with this dial or a black dial with rhodium-plated hour markers and hands. The stainless steel bracelet is slightly cambered, giving the watch smoother lines and offering improved comfort for the wearer. Hand-stitched polished Louisiana alligator leather straps are also available in black to complement the black dial, or in brown for the ivory dial. The heart of the Speedmaster "Broad Arrow" is undoubtedly the new OMEGA calibre 3303 movement, developed by OMEGA and produced exclusively for OMEGA by Frédéric Piguet. The new calibre is a totally new self-winding COSC-certified chronometer movement which benefits from the latest in watchmaking technology. Its column-wheel chronograph mechanism consists of a ratchet wheel with columns that govern the precision operation of various levers for the chronograph functions: start, stop and reset for the central chronograph seconds hand and the hour and minute totalisers (located at 6 o'clock and 3 o'clock respectively). Column-wheel chronographs are widely recognised as the finest chronograph movements available. However, they remain exclusive, since very few manufacturers are capable of producing this highly sophisticated mechanism. The exclusive nature of OMEGA's new movement is further enhanced by OMEGA's proven sprung-balance without index, which offers improved regulating stability. Broad Arrow models are also available with cases and hands in 18-carat yellow gold (with black dial), red gold (with dark blue dial) and white gold (with grey "Rolesium" dial) with a matching 18-carat gold bracelet or hand-stitched Louisiana alligator leather strap (in black for the models in yellow and white gold, in blue for the red gold model).  Omega Men' s Speedmaster Broad Arrow Series Watch.

Omega Watch is one of the world's best-known manufacturers of various high-end watches, most of the company's products being renowned throughout the world both for their high-end features, but also for their equally impressive price tags. And that's also pretty much the case with the series you're about to see as follows, namely the Speedmaster Broad Arrow Rattrapante. First and foremost, it's important to note that the device is built around a very precise Omega caliber, a self-winding chronograph movement with column wheel mechanism and Co-Axial Escapement for greater precision, stability and durability of the movement. Additionally, since we're talking about a self-winding mechanism, it's also quite important to mention the fact that the watch offers a power reserve of around 52 hours, which is quite a good value (after all, we're talking about more than 2 days). Other very important features, common to all the models from the Speedmaster Broad Arrow Rattrapante series are the free sprung balance, with date, hour, minute and continuous small seconds hands as well as the central chronograph hand. Furthermore, the Speedmaster Broad Arrow Rattrapante watch has also been fitted with a domed anti-reflective, scratch-resistant sapphire crystal face. Moreover, the casing has a relatively normal size (44.25 mm in diameter), and is also resistant to water, down to a depth of around 100 meters.

The Speedmaster Co-Axial Chronometer with reference number 311.30.44.50.01.002  is made of stainless steel on a stainless steel bracelet. The Omega Men's Speedmaster Co-Axial Chronometer Steel Black Watch retains its original look but still remains relevant in today's style. An in-house Caliber Omega 3313, self-winding automatic chronometer with co-axial escapement drives this new watch. The Omega gents Chronometer watch in stainless steel features a 44.25mm case with a white dial on a stainless steel bracelet. The Speedmaster Co-Axial Chronometer watch features an automatic movement and Co-Axial Escapement for greater precision.

Omega Speedmaster Day-Date Series replaces one of its chrono subdials with one that displays the date on the dial and day and month indicators within it. This precise chronograph timepiece will also help you keep track of your road training thanks to its tachymeter bezel. The large watch case measures 40mm wide (1.57 inches) and it's matched to a triple-link stainless steel bracelet that mixes brushed and polished finishes. Other features include a 44-hour power reserve, a scratch-resistant and glare-proofed domed sapphire crystal, and water resistance to 100 meters (330 feet)--offering protection from accidental splashes as well suitable for OMEGA swimming, snorkeling, and light recreational diving. This Omega Speedmaster Day-Date Series watch also features the Omega 3606 caliber automatic movement, which has been certified as a chronometer by the COSC (Swiss Official Chronometer Control). Only 3 percent of OMEGA watches produced in Switzerland are "chronometer-certified." To achieve this highly coveted certification, the movements are subjected to numerous tests over a period of 15 consecutive days and nights, in five positions and at three different temperatures.

Brilliantly innovative, Omega Men's Speedmaster Date Series is encased by a scratch-resistant-sapphire dial window. Contrasting hour and minute indexes ensure easy readability, and other technological details include a three-subdial chronograph function, a tachymeter, and a handy date calendar that rests at the three o'clock position.
