The 45.5 mm case is made from blue ceramic. with a blue ceramic bezel featuring a Liquidmetal™ diving scale. A blend of orange rubber and ceramic covers the first 15 minutes. Orange rubber also colours the OMEGA logo on the crown and helium escape valve symbol.

The blue ceramic dial includes an orange GMT track. while the hands and indexes are in 18K white gold with a white Super-LumiNova coating. On the wave-edged caseback. there is a patented ceramic Naiad Lock that keeps the engraved wording in position.

The blue rubber strap includes orange stitching and lining as well as a ceramic foldover clasp. The watch is driven by the superb OMEGA Master Chronometer calibre 8906.
