A watch or clock which automatically sounds at a pre-set time.
Apertures which display both the day of the month (numerical) and the day of the week.
GMT and Worldtimer
A GMT function means that the watch has a second hour hand which completes one full rotation in 24 hours and a 24-hour index on the dial. Particularly useful for wearers who wish to track two time zones.
Watch with digital (or combined analogue/digital) display with several functions, such as alarm, chronograph, countdown timer etc. with optional display of the required mode.

Titanium alloys are light, corrosion-resistant, biochemically inert and able to withstand extreme temperatures. These properties make them particularly appropriate for products in the aircraft, spacecraft and medical sectors. They achieve the perfect balance between solidity, corrosion-resistance and workability. Grade 2 titanium offers a dim grey colour and suits mostly "brushed" finished pieces. It has featured in a number of OMEGA timepieces used for sport and space exploration, where light reflections should be avoided.

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.
