Omega Aqua Terra Worldtimer Review

Omega Aqua Terra Worldtimer

Omega is best known for their tool watches. The legendary Speedmaster and iconic Seamaster practically need no introduction. While dress watches and traditional complications have been part of their history, sports watches remain front and center.

That didn’t stop Omega from offering the best of both worlds with the Aqua Terra Worldtimer. It brings together the Seamaster Aqua Terra’s robust everyday build and anti-magnetic properties with the sophistication of a worldtimer. Get to know this sporty take on the classic complication:

A 15th Anniversary Offering

The Omega Aqua Terra Worldtimer made its debut in 2017 with a limited-edition model made in 950 platinum. Commemorating the 15th anniversary of the Aqua Terra line, this is the first worldtimer watch that the Biel-based brand has produced and is one of only a few Omega timepieces made in platinum.

This Aqua Terra Worldtimer comes in a large 43mm case with a polished bezel, twisted lugs, and a brown leather strap. The most distinguishing feature of this model is its platinum sandblasted dial, which displays the worldtimer, and vertical lines that recall the teak patterns of the Seamaster line. Luminous yellow gold indices and an elegant hand-enameled world map made of sapphire crystal make the watch especially striking.

Created by Louis Cottier in 1932, the Worldtimer is a classic complication that shows all 24 time-zones around the world at a single glance. The Aqua Terra Worldtimer includes 3 quintessential worldtimer elements: a city ring on the outer rim, a central world map that serves as the geographical projection of the earth, and a 24-hour disc, with day-time on a white backdrop and night-time on a dark blue backdrop.

While truly innovative, this first edition wasn’t exactly destined for the everyman – its limited run of 87 pieces and price tag of nearly $50,000 probably have a bit to do with this.

Aqua Terra Worldtimer in Steel and Sedna Gold

Three years later, Omega introduced a standard production Aqua Terra Worldtimer in stainless steel and Sedna gold – much to the delight of fans.

The new version comes at a fraction of the cost and with a beautiful blue dial – at the center of which, is a laser-ablated titanium world map, which has more intricate and refined details compared to the platinum variants’s hand-painted enamel dial.



Straddling the line between elegant and sporty, the dial is in blue and features the same faceted hour markers and hands but with a blue-colored lume and steel surrounds.

At the center is a world map made of a grade 5 titanium plate that has been laser-sculpted to create the crystal blue ocean and the relief engravings of the world’s major land masses. This is surrounded by a 24-hour scale that revolves over the day and a superbly executed outer ring that depicts the 24 major cities in the world.

Instead of big cities like Paris, Geneva, Berlin or Zurich, Omega chose to put Bienne on the dial to represent the Central European Time. This is a choice that ought to be significant for Omega fans, as this small Swiss municipality is where the Omega HQ and its parent company, the Swatch Group, are situated.



The new Omega Aqua Terra Worldtimer falls into two buckets when it comes to movements. The steel editions are powered by the Caliber 8938 with a 60-hour power reserve and an unusual frequency rating of 25,200 vibrations per hour. Complete with the Co-Axial escapement and a METAS certification, this movement is also amagnetic with the ability to resist magnetic fields up to 15,000 gauss.

Meanwhile, the Sedna gold models run on the self-winding Caliber 8939, whose base is the emblematic Caliber 8900 that powers numerous Planet Ocean, Aqua Terra, DeVille, and Globemaster models. Equipped with 39 jewels and a Sedna gold rotor with Geneva waves in arabesque, it provides great stability in the face of shocks.



Both the stainless steel and Sedna gold Aqua Terra Worldtimers come with a choice of three bands: a metal bracelet that matches the case material and blue leather and textured rubber straps that complement the vibrantly colored dial.
