Description

This Speedmaster model has been created in tribute to the golfer Rory McIlroy and provides several unique details in design. In particular, it celebrates the incredible course record of 61 he shot at Royal Portrush Golf Club at age 16 – a moment that helped ignite his career.

The watch follows the style of OMEGA's original Speedmaster from 1957 and 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. When exposed to a UV light, the subdials also reveal the numbers 16 and 61. 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. At the heart of this chronograph is the OMEGA Co-Axial calibre 9301.

    Sapphire Crystal

Yellow Gold

Gold in its pure form (24K) is slightly reddish yellow and very soft. It is usually alloyed with other base metals for a diverse variety of uses. Considered to be the premium standard in watch and jewellery making, 18K golds (with at least 75% pure gold) provides the ultimate balance between purity and usefulness. Traditional 18K yellow gold is alloyed with copper-silver and offers an excellent resistance to corrosion, while being highly bio-chemically inert. It provides a beautiful hue that suits wearers even with sensitive skin.

Sapphire Crystal

To really appreciate the finer details of a timepiece, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective treatment. Before the machining and finishing processes take place, the sapphire crystals are produced under the Verneuil process, also called flame fusion. It involves the melting of the raw substance using oxyhydrogen flame and the crystallisation of the melted droplets to form a cylinder. Graded 9 on the Mohs-hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-proof and very hard, ensuring an unhindered vision at all times.
