Description

Characterised by its thin and classic case, the Trésor line was first launched by OMEGA in 1949. More than half a century later, the newest models in the collection still remain true to that timeless design.

This model celebrates the 125th anniversary of the OMEGA name and has been created with a number of unique touches. The 40mm timepiece includes an 18K yellow gold case with a rare red enamel dial that links to OMEGA’s iconic brand colour, as well as 18K yellow gold domed indexes and hands. The caseback includes an 18K yellow gold anniversary medallion filled with red enamel. This is surrounded by a traditional engraving known as damaskeeing – the same that was originally used on some 19-ligne calibres.

The watch is presented on a burgundy leather strap and is driven by the OMEGA Master Chronometer Calibre 8929 – the first manual-winding Master Chronometer movement.

    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 gold (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.
