Pre-Basel 2012 Omega Seamaster Aqua Terra GMT

This is a pre-Basel stunner from Omega; the Seamaster Aqua Terra GMT.

The watch has the GMT acronym at the end of the title because of its GMT complication and it’s a first for Omega.

In addition to the central hour, minute and seconds hands, (all in white or red gold) there is a red tipped GMT hand, also in white or red gold, which completes one rotation every 24 hours, so you can simultaneously keep track of time in two time zone and can also be used for compass orientation.

The case is 43mm in a choice of metals: 18k red gold or stainless steel or, in a
bi-metalled version in 18k red gold and stainless steel.

Like many Omega models, the sapphire crystal on the caseback provides a window on the Co-Axial movement inside.

The watch comes on a bracelet that matches the metal of the watch case or alternatively with a black, brown or blue leather strap.

The teaked dial pattern, typical of the Aqua Terra series, is present in this model and is designed to resemble the teak decks on a luxury yacht.

The polished indexes and hands are coated with white Super-LumiNova.

Co-Axial calibre 8605/8615

Developed by the late George Daniels, the co–axial is the first practical new watch escapement to be developed in some 250 years.

The Co-Axial escapement in the Omega calibre is used in conjunction with a free sprung-balance and its function differs considerably from that of a conventional lever escapement with index.

The watch’s rate is adjusted by modifying the moment of inertia of the balance by means of two gold regulating micro screws embedded in the circular balance.

This design avoids the disturbing effects of contact between the balance-spring and the index pins and therefore ensures that the stability of rate offered by the Co-Axial escapement is maintained over long periods of use.

The result is reduced friction which means that there is almost no need for lubrication; the Co-Axial calibres have long service intervals and just for good measure, the Seamaster Aqua Terra GMT comes with a four-year warranty. 

No pricing as yet but the white gold accents on the indexes and hands are likely to push it up higher than other models in the Aqua Terra range.
