This 43 mm Worldtimer watch model from Omega includes a polished case and bracelet in stainless steel.<br /><br />The exterior section of the dial is sun-brushed blue and includes vertical teak stripes and a circle of global destinations printed in red (GMT), silvery (+1h in summer) and blue (places without daylight savings).<br /><br />The centre of the dial contains a 24-hour glass ring, with light blue to indicate daytime and dark blue to indicate night. The vision of Earth is created on a grade 5 titanium plate. This has been laser-ablated to create the blue ocean, leaving a relief of the continents. The contrasting colours of the Earth’s surface are obtained naturally by the laser’s chemical reaction.<br /><br />Inside, the Worldtimer is driven by the Master Chronometer Calibre 8938.<ul><li>43mm stainless steel case with a screw-in crown and transparent case back</li><li>Synthetic domed sapphire crystal with a highly scratch-resistant and anti-reflective treatment</li><li>Between Lugs: 21mm</li><li>Blue dial with a date window at 6 o’clock, luminous accents, and world time</li><li>Rhodium-plated finish with Geneva waves in arabesque</li><li>Stainless steel bracelet</li><li>Master Chronometer Certified Calibre 8938 automatic movement/approved by METAS/self-winding movement with Co-Axial escapement</li><li>Free sprung-balance with silicon balance spring; automatic winding in both directions</li><li>Anti-magnetic/resistant to magnetic fields reaching 15,000 gauss</li><li>Swiss made</li><li>Water resistant up to 15 bar (150 metres / 500 feet)</li><li>Omega Style #: O22010432203001</li></ul>
