Steel-Green Ceramic or Titanium, The New Omega Seamaster Aqua Terra Worldtimer 2023 Editions

The most complicated watch in the casually-chic AT collection, the Omega Seamaster Aqua Terra Worldtimer has been around for some years now, undergoing several updates since its introduction in 2017 – back then in a highly luxurious platinum edition. Now part of the permanent collection in either stainless steel or Sedna gold, with a blue central world map, the complex and travel-oriented watch of Omega is about to move in new, bolder and sportier territories, with the launch of 3 new models for 2023. Stainless steel combined with green ceramic or monochromatic titanium, the choice is yours. 

Since its debut in 2017, the Aqua Terra Worldtimer has remained a rather confidential piece in the otherwise classic AT collection – a watch that can be seen as the brand’s all-rounder, a casual-chic watch that can do it all, week or weekends. That being said, the inaugural model surely made an impact, but it wasn’t exactly what we were expecting to see from Omega… An 87-piece limited edition, with a 43mm platinum case, gold markers and hands, hand-crafted enamel world map, textured dial and the usual complex display of a world timer watch. Not the easiest. In 2019, Omega corrected this with models for the permanent collection, either made in steel (on strap or bracelet), with a blue dial or in Sedna gold with a silver dial. And both featured a textured, realistic world map in the centre. Overall appealing, and quite classic for this type of watch, despite a sportier attire than usual.

This year, and without reinventing entirely the concept of the collection, Omega launches 3 new references that are more audacious, more colourful or on the contrary monochromatic, sportier and yet quite appealing. There’s a pair of steel models, with touches of green all around, as well as a lightweight, low-key titanium model.

Shared Specs

All three models share the same basic specifications, and are in line with the models introduced by the brand back in 2019. This means a signature Omega case with twisted lyre lugs, an asymmetrical shape (like always with the AT collection, which doesn’t feature crown guards), a conical crown and a pretty wide smooth bezel to frame the complex dial. What has to be taken into account is the size. The ATWT (Aqua Terra WorldTimer) is a large watch, the largest within the collection, as it measures 43mm in diameter, 14.1mm in height and 50mm lug-to-lug – not overly long considering the diameter. The crown screws down, and so does the caseback, both guaranteeing 150m of water-resistance.

The dials, whether on the previous classic models, the new steel versions or the unprecedented titanium edition, all share the same layout. Typical of a worldtimer, it is composed of central hours, minutes and seconds hands, and a date at 6 o’clock. As for the travelling function, it relies on a central world map, engraved in a pretty realistic manner by laser-ablating continents and colours on a grade 5 titanium surface, showing Earth as seen from the North Pole. It is framed by a 24h disc under a hesalite glass, rotating on its own axis, and with day and night sections. Finally, a city ring frames the dial, with London highlighted in red – to highlight Greenwich Mean Time, now more formally known as Universal Time Coordinated (UTC). And there’s even a small Easter Egg, as the Central Europe time zone is depicted by Bienne, home city of Omega in Switzerland.

Powering these 3 new Aqua Terra Worldtimer watches is the in-house calibre 8938. Based on the well-known and powerful 89xx architecture, it is an automatic movement with 2 barrels for a 60h power reserve. And being an Omega engine, it features a free sprung-balance with a silicon balance spring and a co-axial escapement. As such, it is Master Chronometer-certified and boasts a high level of resistance to magnetism. The decoration is typical of the brand, with Geneva stripes in arabesque and blackened screws. Note that all adjustments, including the worldtimer function, are done by the crown.

The Steel and Green Ceramic models

Released as a pair of new models, the Seamaster Aqua Terra Worldtimer here becomes bolder, more colourful and more fun with the addition of green accents all around. First, the bezel is made of brushed and polished green ceramic, which pairs with the equally green dial. The latter is typical Aqua Terra, with a striped pattern as a teak deck. In this edition, the hands and indexes are made in 18K Moonshine Gold, and all cities (except London) are also gold-coloured.

This steel and green ceramic Seamaster Aqua Terra Worldtimer is available on a green integrated rubber strap with grey stitching, an additional decorative link in polished steel, and a polished-brushed fold-over clasp (reference 220.32.43.22.10.001), priced at EUR 11,500. It is also available on a 3-link polished-brushed steel bracelet with a folding clasp (reference 220.30.43.22.10.001), priced at EUR 11,800.

The Titanium Worldtimer

The last edition might well be the most surprising, combining complication and lightweight, technical materials as well as a monochromatic look. Here, the 43mm case is made of brushed grade 2 titanium – which will certainly make this watch more comfortable – and paired with a brushed black ceramic bezel. The dial of this edition is also rather impressive, since it has been made entirely by laser ablation over titanium. The result is a combination of matte surfaces and 3D-like mentions on the dial. Following the b&w theme, the hands and markers are blackened and the cities are rendered in white. Even these markings have been done by laser, and apart from the red London, there are no transferred elements.

The titanium Omega Seamaster Aqua Terra Worldtimer (reference 220.92.43.22.99.001) is worn on a black integrated rubber strap with grey stitching, an additional decorative link in brushed titanium, and a brushed fold-over titanium clasp. It is priced at EUR 13,300.
