Omega has always been driven by a pioneering spirit; in fact, no watch company in the world holds more records for accuracy. Their watches have been the timepiece of choice for some of history’s greatest explorers—from deep-sea divers to astronauts.

Brimming with beauty—and stellar features—this Omega Seamaster Aqua Terra is a distinguished dress piece that’s equally ready for action.

First, behold the gorgeous 18K rose gold bezel. It catches the eye and makes a lovely accompaniment to the raised rose gold index hours upon the black-colored dial. In addition, note the Omega logo upon 18K rose gold screw-down winding crown.

The silvered subdials are prominent against the dark dial and deliver a small seconds at 9 and chronograph functions that include a 30-minute counter at 3 and a 12-hour counter at 6 as well as a center seconds hand.

Along the outer edge of the dial we encounter a handy pulsations scale to measure your heart rate and there is a date window classically positioned at 6.

As a highly accurate COSC-certified chronometer, we find the self-winding co-axial automatic Omega 3301 caliber at the heart of this Seamaster. It sports 33 jewels and a 52-hour power reserve.

The stainless steel case measures 42.2 mm in diameter, 14.3 mm in height, and rests upon a stainless steel bracelet with a folding buckle. Look for a solid caseback, 150 m / 15 atm water resistance, and a scratch-resistant sapphire crystal.

From its legendary accuracy to its luxurious stylings, we believe this Seamaster Aqua Terra by Omega will make a thrilling addition to your collection.

Standout feature(s): Highly accurate COSC-certified chronometer; luxurious 18K rose gold bezel and winding crown; handy pulsations scale to measure heart rate.
