"The OMEGA Spacemaster Z-33 : welcome to a world of discovery !"
  • Speedmaster Spacemaster Dark Dial view
    The black LCD screen with red segments is illuminated by the LED backlight which adapts automatically to ambient luminosity. Night legibility is impressively facilitated by the strong luminescent material on the large white hour and minute hands and the hour markers on the dial.
  • Speedmaster Spacemaster Caseback
    Continuing the watch's high-tech feel is the titanium casebody with a double-wall caseback. The inner caseback ensures water resistance to 3 bar (30 metres / 100 feet) while the outer one acts a resonance chamber to amplify the sound of the alarm. It features a brightly polished Seahorse, ‘Ω’ and ‘Speedmaster’ inscriptions against a mat background.
  • Speedmaster Spacemaster Side View
    Complementing the analog hour, minute and seconds hands, the digital features can be controlled by the crown and by four pushers. Among these are UTC plus two time zones, an alarm and a perpetual calendar. There is also a chronograph function and a countdown timer.

Grade 5 Titanium

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 5 titanium offers a bright grey colour that is close to that of stainless steel, and suits both "brushed" and "polished" finishing.

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.

The advantages
of this watch

When it comes to reliability there’s no matching a movement bound by natural law. This watch’s internal workings uses the very precise frequency signal of a quartz crystal to display time. The movement is powered by a battery and extremely accurate. What’s more it takes up minimal space, allowing for slimmer watch designs.
