Description

The “Big Blue” is a combination GMT and divers' watch that delivers bold style and innovative design. 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.

  • Helium escape valve

    Decompression system which allows helium to escape from inside the watch when the watch is worn for professional use in pressure chambers. (Long-term underwater work, crude oil exploration, etc.)

  • Liquidmetal™

    Liquidmetal™ Liquidmetal™

    Liquidmetal is an alloy which is considerably harder than stainless steel yet bonds seamlessly with ceramics. The blended materials are particularly resistant to scratching and corrosion.

  • Screw‑in crown

    Screw-in crown Screw-in crown

    Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.
