This replica Seamaster Ultra Deep orange takes the Planet Ocean concept to its engineering extreme. The Ultra Deep line was born from the record-setting dive to the bottom of the Mariana Trench, and this orange-dial version translates that deep-sea DNA into a wrist-worn format. Omega built the Ultra Deep around a case that is visibly thicker and more heavily constructed than standard Planet Ocean references, using materials and sealing systems derived from the actual research submersible prototype.

Case & Movement Specs

• Dial: orange with luminous indices
• Case material: steel, reinforced construction
• Bezel: uni-directional with ceramic insert
• Crystal: thick domed sapphire
• Strap: integrated rubber with deployant clasp
• Movement: automatic Co-Axial Master Chronometer
• Functions: hours, minutes, seconds, date

The orange dial is not a subtle choice. It provides extreme visibility both above and below the waterline, matching the safety-orange used on professional diving equipment. The luminous fill on the hands and indices glows strongly in dark conditions, and the matte finish on the dial surface prevents reflections that could obscure the time reading at depth.

Caliber Breakdown

The Master Chronometer-grade movement inside the Ultra Deep meets testing standards that exceed COSC certification. The automatic winding system powers a time-and-date display without the additional complication of a chronograph, keeping the dial uncluttered and purpose-focused. The silicon balance spring provides resistance to magnetic fields up to 15,000 gauss, which matters in real-world environments where electronic devices constantly surround the wearer. Compare this orange-dial Ultra Deep against the orange-bezel Ultra Deep version to see how the same color applied to the bezel versus the dial changes the overall character. Both sit in the Seamaster range as the most extreme offerings.

How It Compares

Standard Planet Ocean 600M models max out at 600 meters of water resistance. The Ultra Deep pushes that specification dramatically higher, which required fundamental changes to case geometry, crystal thickness, and gasket design. The result is a watch that wears larger and thicker than a regular Planet Ocean, but carries engineering credentials that no other production diver can match. Buyers choosing between a standard Planet Ocean and an Ultra Deep are deciding between everyday versatility and maximum capability. This replica Seamaster Ultra Deep orange makes that capability statement in the loudest color available.
