The Speedmaster 57 is a modern ode to Omega's first generation of Speedmasters. It features a case with straight lugs and a bezel with the tachymeter scale engraved. The same features were found on early versions of Omega's iconic chronograph, while later models feature the swirling 'lyre' lugs and a bezel with separate inlay still in use today.

Reference 331. was introduced in 2019 in tribute to the golfer Rory McIlroy and provides several unique details in design. In particular, it celebrates the course record of 61 he shot at Royal Portrush Golf Club at age 16 – a moment that helped ignite his career.

The watch is based on the 331. but features a sun-brushed champagne dial in PVD yellow gold with a blackened outer zone and minute track transferred in yellow gold colour. There is also a date window at the 6 o’clock position.

The unique subdials include a small-seconds counter at 9 o’clock and a 12-hour and 60-minute chronograph recorder at 3 o’clock. The brushed bezel, with its tachymeter scale, is mounted on a 41.50 mm 18K yellow gold case, which is presented on a matching bracelet. It is powered by caliber 9301.
