Description

Omega Seamaster Planet Ocean Ultra Deep 216.30.46.21.04.001 in a 45.5mm stainless steel case, powered by the Omega caliber 8912 Master Chronometer movement. This reference represents Omega’s most extreme production dive watch, derived directly from the record-setting Ultra Deep prototypes that reached the Challenger Deep.

This example features the highly desirable white dial configuration with bold blue Arabic numerals and matching blue ceramic bezel, creating a striking and highly legible contrast. The dial is clean and crisp, with broad arrow hands and applied indices filled with luminous material for excellent underwater visibility.

Engineered for true professional use, the Ultra Deep is rated to 6,000 meters (20,000 feet) of water resistance, utilizing Omega’s O-MEGASTEEL construction for superior strength and corrosion resistance. The watch is METAS-certified, offering resistance to magnetic fields up to 15,000 gauss while maintaining exceptional chronometric performance.

This set includes the original wooden presentation box, Omega travel case, warranty cards, leatherette wallet, and two (2) additional bracelet links. The bracelet will fit up to an 8.5 inch wrist.

Powering the watch is the Omega caliber 8912, a time-only automatic movement with twin barrels in series, delivering a 60-hour power reserve. Finished with Omega’s signature arabesque Geneva waves, the movement is Master Chronometer certified, ensuring durability, precision, and long-term reliability in even the most demanding environments.
