OMEGA unveiled at BaselWorld 2012 a new variant of its Seamaster Aqua
Terra, the Seamaster Aqua Terra GMT. As indicated by its name the
Seamaster Aqua Terra GMT is a dual time watch which can keep track of
two different time zones. The main hour, which rotates at the usual
rate of once every 12-hours, is used to keep local time. A second hour
hand with a red and white triangle head which completes one rotation
every 24 hours, is use to keep track of the second time zone. Since it
is reports "military" time it will also allow you to keep track of
whether it is day or night in the second time zone.
OMEGA Seamaster Aqua Terra GMT. The Seamaster Aqua Terra
GMT dial has the attractive "Teck Concept" dial, which is highlighted
with vertical lines to resemble wooden decks on luxury boats. This new
dial was first seen with the refresh of the Aqua Terra line-up in 2008.
The case is 43 mm in diameter and available in 18 Ct red gold,
stainless steel or, in a bicolor version in 18 Ct red gold and stainless
steel. The watch is
available with either a bracelet in the same metal as the watch case or
with a black, brown or blue leather strap.

First dual time co-axial watch. The Seamaster Aqua Terra GMT is
powered by the self-winding Co-Axial calibre 8605/8615 movement. This is
the first of OMEGA Co-Axial movement to be equipped with a GMT
complication. The movement is rated as a chronometer, meaning it was to
tested to deviate by not more than +4 second or -6 seconds per day. A
sapphire crystal on the screw-in caseback allows a clear
view of the movement from the back of the watch.
The Co-Axial escapement in the OMEGA calibres is designed avoids the
disturbing effects of contact between the balance-spring and the index
pins. The result is reduced friction which means that there is almost no
need for lubrication which results in Co-Axial calibres have long
service intervals.
