The story · Since 1957
Omega built the Speedmaster '57 around the straight lugs, bare crown and steel tachymeter bezel of the first 1957 Speedmaster, then in 2022 gave it a hand-wound movement that made it thinner than the Moonwatch, at 12.99 mm.
12.99 mm
12.99 mm: thickness of the 40.5 mm Speedmaster '57 ref. 332.10.41.51.01.001, against 16.17 mm on the 41.5 mm ref. 331.10.42.51.01.001, which Omega lists as no longer available

The first Speedmaster, reference CK2915, arrived in 1957 and was made until 1959. It was conceived for racing drivers, with the tachymeter scale moved from the dial onto a steel bezel, straight lugs and Broad Arrow hands. Every Speedmaster '57 is a modern evocation of this watch, not a replica.
Omega unveiled the Speedmaster '57 Co-Axial at Baselworld 2013 with a 41.5 mm symmetrical case and straight lugs. Inside was the automatic column-wheel calibre 9300, which put the hours and minutes counters on one sub-dial at 3 o'clock. It came in steel, titanium, two-tone and 18k yellow or red gold, with Alpha hands rather than Broad Arrows.
At Baselworld 2015 Omega corrected what collectors had criticised, fitting Broad Arrow hands and recessed markers filled with Vintage Super-LumiNova (ref. 331.10.42.51.01.002). The leather version came on a honey-brown Barenia strap. Omega promoted it on a billboard with George Clooney under the line 'George Clooney's Choice'.
For the Speedmaster's 65th anniversary Omega rebuilt the line at 40.5 mm and 12.99 mm thick around the hand-wound Master Chronometer calibre 9906. The eight steel models offer a black sandwich dial plus blue, green and burgundy, on leather straps or a flat-link bracelet modelled on the 2019 Apollo 11 watch. Water resistance dropped from 100 m on the 2015 model to 50 m.
Long-time Omega ambassador. In 2015 he appeared on Omega billboards wearing the Speedmaster '57 with Broad Arrow hands. In August 2022 he wore the blue-dial 40.5 mm model at Omega's party during the European Masters in Crans-Montana, previewing a campaign in which he drives a vintage car near Lake Como wearing ref. 332.10.41.51.03.001. Campaign and event wear; Clooney said he loved it as 'the epitome of class'.
The South Korean actor of Crash Landing on You fronted the 2022 Speedmaster '57 launch campaign beside Clooney, photographed in South Korea wearing the 40.5 mm steel model with a black dial. Campaign wear.
2022. At the Omega European Masters golf week in Crans-Montana, George Clooney previewed his Speedmaster '57 campaign wearing the blue-dial model, joking that he was not quite as old as the '57, being born in 1961.
2015. Omega ran a giant Sunset Boulevard billboard in Los Angeles showing George Clooney on a classic motorcycle in the desert, wearing the new vintage-dial Speedmaster '57 under the slogan 'George Clooney's Choice'.

No reference matches.
Omega Speedmaster '57 references use 19 mm or 20 mm depending on the reference and case size, so check yours in the list below. The most common is 20 mm (8 of 9 references with a known width). The Omega Speedmaster '57 ref. 332.12.41.51.03.001, 332.12.41.51.10.001 and 4 more take 20 mm (listed by the maker).
No. 2 different lug widths appear across the line, often by case size or generation. Check the reference engraved on the case back or between the lugs.
20 mm. Omega lists 20 mm between the lugs for ref. 332.10.41.51.01.001, and Monochrome gives 20 mm at the lugs for both the flat-link bracelet and the leather strap.
The width is the same: Omega gives 20 mm between the lugs for the 41.5 mm model too. The older case is slightly longer (50.00 mm lug to lug against 49.64 mm) and much thicker (16.17 mm against 12.99 mm), so curved-end straps may sit differently.
The flat-link bracelet runs from 20 mm at the lugs to 15 mm at a folding clasp with a 2.3 mm comfort release extension. The leather strap goes from 20 mm to 16 mm at a pin buckle.
Monochrome advises the bracelet, about 400 euros more, then adding aftermarket straps, since buying a steel bracelet later from a boutique is harder. Fratello gave the same advice for the 2015 model.
No. It is smaller in diameter but longer: Monochrome measured 49.6 mm lug to lug, about 2 mm more than the current Moonwatch, so the '57 sits long on the wrist while the Moonwatch sits wide. Omega lists 47.46 mm lug to lug for a current 42 mm Moonwatch.
The gap between the two lugs that hold the strap, in millimetres. A new strap must match it exactly: 20 mm lugs take a 20 mm strap.
Most watches use spring bars, so any strap of the right width fits. Many smartwatches use their own band system instead, such as Apple Watch bands or Garmin QuickFit.
