As a special function of the watch, the world time can be easily controlled with one watch, making it the best companion for frequent flyers and travelers all over the world. The worldtime display of each watch brand also has its own characteristics in terms of design and operation. Among the many world timer watches to choose from, I think the most important one is the Omega Seamaster Aqua TERRA 150M GMT World Timer. 2023 also coincides with the 75th anniversary of the birth of the Seamaster series, which was upgraded in May last year, and the "Summer Blue" series was launched in August, including a special ice blue tone of the AT 150 world.

The Omega Seamaster Aqua TERRA 150M GMT was born in 2017, when Omega knew that in order to accurately and conveniently control the time in various time zones of the world, the worldtime watch was favored by watch lovers, so it released this series of works, enriching the product line of the Seamaster series with complications.
In the new product upgrade in May last year, OMEGA also focused on the appearance of the AT150 Worldtimer, and the overall details were depicted, including the innovative material applications of the titanium case and ceramic bezel, as well as the green disc, black and gray disc, and the Summer Blue special blue disc to be introduced today, thus providing more rich choices.
A real picture of the watch
Judging from the actual Aqua Terra worldtimer, its outstanding appearance design is one of the best in the entire Summer Blue series. In terms of dimensions, the watch features the iconic symmetrical case design of 43 mm and a thickness of 14.1 mm. The size alone may make some cousins think that it is too large, but in fact, it is indeed more obvious to make the indications on the board of the Universal Time more clear.
The stainless steel case is finished with brushed wires on the sides of the case, while the front of the case and the angular edges are heavily polished to extend to OMEGA's signature twisted lugs. It is worth noting that this piece does not replace the ceramic ring like the previous green disc and the titanium case black disc model, but uses the stainless steel bezel, which I understand to be Omega's desire to create a more holistic and harmonious visual effect with a metallic luster and the special dial color of Summer Blue.
This 75th anniversary Summer Blue collection features a unique variation of summer blue tones on the dial with different water-resistance levels for each watch. The shallower the waterproof depth, the more ice blue the surface of the disk, just like the sea level when you look up when you are snorkeling, and the color of the 6000-meter deep dive of the Seahorse King Ultra Deep is dark blue, symbolizing the dark deep sea polar region. The Seamaster Aqua Terra is water-resistant to 150 metres, and its ice-blue dial with teak deck decoration is rich in texture and cool, representing the light blue sea level. Omega also has a gradient outwards centered on the central globe and a sunburst effect. At the same time, in order not to affect the overall vision of the plate, Omega also deliberately made the date display at six o'clock into an ice blue background.
The design of the map of the Northern Hemisphere, centered on the North Pole, in the center of the dial, is also the absolute highlight of the watch. Powered by grade 5 titanium, OMEGA uses laser ablation to engrave the texture and texture of the terrain, and then uses laser technology to color it to create a sandblasted blue ocean and a silver relief to shape the continent's land plates. In the details of the earth, it can be seen that Omega has also restored the appearance of the high-altitude area, including the slight curved surface effect of the earth to mimic the curvature of the real earth. Compared with the central map of the old AT150 World Time, there is no doubt that the new model is more refined and delicate.
The operation of the watch's world time function is also intuitive and distinctive, which is different from the regular world time. First of all, the outermost two circles of the city circle on the hippocampus disk can not be rotated, only the inner ring is made of plexiglass 24-hour scale ring can be moved, but as long as the wearer at any time, the 24-hour circle is aligned with the local time you are in, for example, Beijing is 14 o'clock in the afternoon, and the map is aimed at Beijing at 14 o'clock, and the accurate time of the world is in control. When traveling, all you need to do is pull out the crown and set the hour and minute hands to the local main time zone, and the world time is still 24 hours in the inner ring, with a light blue scale for the day and a dark blue scale for the night. Omega's use of this reference to Universal Time is both excellent and easy to use.
The rhodium-plated hands and indexes on the dial are coated with light blue Super-LumiNova. The picture above shows the luminous effect of the watch.
In terms of movement, the Omega Co-Axial Master Chronometer calibre 8938 continues to be used, as the 8900 calibre equipped with the World Time module, there is no need to worry about the performance of the Master Chronometer certification, and there is also a silicon balance spring on the configuration, which provides the watch with anti-magnetic ability to resist 15,000 gauss, the daily error is controlled at 0/+5 seconds, and the full chain has a 60-hour power reserve. The Summer Blue does not have a back, but instead uses a unique and monumental secret bottom design, with the ground cover engraved with the logo of Poseidon holding a trident and two seahorse mounts.
The watch also comes with an ice blue rubber woven strap of the same color as the dial, and Omega also has a stainless steel bracelet version to choose from, but many watch friends have expressed their preference for this ice blue tape style, and my suggestion is that you can start with both, one watch and two straps, to meet different wearing needs.
Summary: This Omega Summer Blue Seamaster AT World has been introduced to my cousins. In terms of physical effects, the new ice blue color combination and the refreshing and cold visual effect give new vitality to this watch, which has been loved by watch friends since its launch.
And this watch is not only good-looking, but also easy to use, in fact, many watch friends when they first contact the world, they will feel that it is very complicated, do not know how to adjust, but Omega this function is really complex but simple, very practical, and the central dial of the earth design, will give the wearer a feeling that the world time is only in your hands, combined with the Seamaster series AQUA TERRA itself formal wear without losing the casual and versatile attributes, in the same price of watches, it will be a good watch choice.
