The World on Your Wrist: A Closer Look at the Omega Seamaster Aqua Terra Worldtimer

When a watchmaker introduces their new watch to the world, it's the culmination of a series of events. Each premiere is the icing on the cake made of special ingredients: historical background, care, and knowledge passed down through generations, including the characteristic traits of predecessors evident in this latest rendition. Sounds, and in many ways and factors, it genuinely is the way we describe families.

And indeed, the process is strikingly similar: for a successor to be exemplary and carry on the family tradition, they should incorporate all the best that a particular family has and, whenever possible, bring something new to the table, as well. Now, let's check how this genetic formula of success applies to our featured OMEGA Seamaster Aqua Terra 150M Co‑Axial Master Chronometer GMT Worldtimer.

The extended family: the OMEGA main collection

The OMEGA main collection rests on four foundational pillars, each pivotal in supporting the many directions this famous Swiss watchmaker takes. These four pillars are:

• Seamaster - a collection of diving/nautical watches
• Speedmaster - a collection of chronograph watches
• Constellation - a collection of luxury watches and,
• De Ville - a collection that specializes in classic/dress watches

Each of these pillars has unique features that make it easily recognizable and distinguishable from the others. However, all of them have authentic OMEGA genes, which are clear signs that they belong to the same extended family. To mention just a few: historic success/proven in their individual fields background, Co-Axial technology, METAS certified movements, and all are built using premium materials and supreme craftsmanship.

The look and feel of the Quick Release Tapered Milanese Mesh Polished Strap enable a full embrace of the ultimate elegance of the OMEGA 150M Co-Axial Master Chronometer GMT Worldtimer.

The nuclear family: the Seamaster line

The Seamaster collection's history began in 1948. The founding father of the Seamaster family saw the light of day to celebrate OMEGA's 100th anniversary. Fast forward to nowadays, there are hundreds of different Seamaster watches available. Even though, due to their elegant lines and smaller dimensions, some of them may seem more like dress watches, there is one trait that connects all watches from the Seamaster collection. It's the original idea to create a sports watch that is equally adaptable and resilient in both water and on land.

In the decades that followed, Seamaster engineers built on the original idea using contemporary materials and produced a number of legendary watches, securing the Seamaster line as one of the four foundational pillars of OMEGA's longevity and progress. Among others, memorable Seamaster watches include the 1957 Seamaster 300, Seamaster 300M Chronograph, Seamaster 120 Big Blue, the Seamaster 600 “Ploprof”, and one of the contemporary heirs, the featured Seamaster Aqua Terra Worldtimer.

 One cannot go wrong with a blue elongation of the OMEGA Seamaster Aqua Terra 150M Co-Axial Master Worldtimer. When paired with the Quick Release FKM26 Slate Blue FKM Rubber watch strap, the OMEGA Worldtimer exudes a highly appealing modern-casual vibe.

OMEGA Seamaster Aqua Terra 150M Co‑Axial Master Chronometer GMT Worldtimer

The original Seamaster Aqua Terra Worldtimer watch was released in 2017. This inaugural Worldtimer was designed as OMEGA's premier watch to serve as a bridge between its sports and dress watches, combining the best of both worlds. It was a highly limited-edition platinum-cased model (only 87 were made), released to celebrate the 15th anniversary of the Agua Terra collection.

As expected, this unique model in the OMEGA catalog instantly became the talk of the day. Since the initial interest did not fade and demand remained high, OMEGA followed up, among other models, with a standard production model, our featured OMEGA Seamaster Aqua Terra 150M Co‑Axial Master Chronometer GMT Worldtimer Reference 220.12.43.22.03.001. It is part of the 2019/2020 release of the steel-case Worldtimers, designated to introduce the high-end concept of a worldtimer watch to a more accessible luxury market.

Dial

The dial of the steel-cased 2019 OMEGA Seamaster Worldtimer is breathtaking, to say the least. The color choice worthy of a dress watch, combined with a 3D appearance and perfect readability, and authentic features (a Worldtimer complication at the center of them) characteristic of a Seamaster, earns this model the title of a genuine cross between a dress and a sport watch, using the best of both worlds.

This gorgeous dial has an outer section in a sun-brushed dark-to-light blue shade and features vertical teac stripes characteristic of the Seamaster series. The outer ring is fixed and contains 24 major cities that correspond to 24 time zones. Listed cities are written in varied colors to differentiate those that observe Daylight Saving Time (DST) from those that do not, and to highlight the reference time zone.

The inner section is a story of beauty and function in its own right. Its outer ring is a 24-hour scale divided into two 12h parts, a light blue/silver one to indicate day and a dark blue one to indicate night. This is a rotary ring, connected to the minute hand and follows its rotation, completing the 24-hour circle every day. The Worldtimer operates as follows: the hour hand is set to a local city, while the 24-hour ring shows the corresponding times for the other 23 cities. A straightforward, user-friendly yet precise way to read the time at a glance.

The central section of the dial is a miniature work of art. It's dominated by a world map, a miniature one, but done with utmost precision and craft that it depicts so many details. The map is made of grade 5 titanium plate, and all the details, such as the mesmerizing blue oceans and reliefed continents displaying all significant land masses, are laser-engraved. All the colors and textures present are not painted; they are laser-ablated, creating a stunning 3D effect of the world viewed from the North Pole.

MiLTAT Olive Brown Distressed Leather Watch Strap, with its extra-soft feel, is an ideal pairing for all those who love wearing their beloved OMEGA Seamaster Aqua Terra 150M GMT Worldtimer for extended periods. Matching the color of the continents creates yet additional aesthetic value.

The Mechanism

Beauty in itself, no matter how encompassing, is only one part of the value of the 2017 Omega Seamaster GMT Worldtimer. What drives it completes the package: a trusty OMEGA 8938 caliber, a METAS-certified Master Chronometer with Co-Axial escapement. 8938 caliber boasts resistance to magnetic fields up to 15,000 gauss, and a 60h power reserve. All this with a GMT and Worldtimer complication showing 24 time zones all at once. A truly special timekeeping capability and an ingredient that makes this Seamaster chronometer even more unique.

The Charcoal black of the Alcantara Fabric Quick Release Strap is exactly what the OMEGA Seamaster Aqua Terra Worldtimer needs to fit perfectly into any casual yet highly elegant setting. 

Final thoughts

OMEGA Seamaster Aqua Terra Worldtimer is an attention-grabber with exceptional technical features and a rare pairing of complications. More than enough to be called a truly special watch. Still, it has one more ace up its sleeve, 21mm lugs. Such a special size makes it easier to swap straps, allowing endless pairing possibilities for strap style, material, and pattern. As a result, the 2017 Omega Worldtimer, with an adequate strap pairing, can be worn across different occasions, travels, and outings it's primarily designed for, formal events, its beauty fits perfectly, as well as business wear in any setting around the world.
