Omega burst back on the scene recently with several new timepieces that included among them the “Omega Seamaster Aqua Terra Worldtimer Master Chronometer” in stainless-steel. This watch has now become much more affordable, but beyond that in many ways it has improved in detail and looks compared to its previous platinum version.


It took three years, but Omega has finally released a stainless-steel version of this model. Initially this watch was put on the market only in a made out of platinum edition (Ref#:, which you can read more about here.

Now this new version comes in a 43mm case made of stainless-steel with a transparent exhibition case back, which allows to view the inner workings of the mechanical movement. It also comes equipped with a screw-in crown and short wide lugs that provide a very comfortable wrist fit. All topped by a domed scratch-resistant sapphire crystal with an anti-reflective treatment on both sides. Water-resistance on this watch can reach up to 150 meters (500 feet).


Time is exhibited on a “grand feu” blue dial that features an impressive laser-ablated titanium world map in relief at its center core; instead of handcrafted on vitreous enamel like the platinum version was done.


Using stainless-steel applied hour index markers and a pair of central steel hands to point out current time. There is also a blue date aperture that blends well with the rest of the dial, while using white numerals for visibility at the 6 o’clock position.

As a world-timer watch it’s been equipped with a fixed cities disc and a 24-hour home-time wheel. To indicate seasonal time changes, the cities on the world disc have been color-coded: white symbolizes cities enjoying summer-time (+1h in summer); while light-blue is the color for places without daylight savings; and the city in red (London) is the GMT reference.

Typically world-timer watches use the cities of Paris or Geneva to represent the time-zone of GMT +1, but this model has replaced those cities with Bienne, which is the Swiss city where Omega is headquartered.
