Omega Seamaster Aqua Terra 150M GoodPlanet GMT

The Omega Seamaster Aqua Terra 150M GoodPlanet GMT has a fresh, marine look about it, with its white dial and blue highlights. The case is in titanium, 43 mm in diameter, and quite chunky at 14.15 mm thickness. Its finish is mainly brushed, with polished details and bezel. The water resistance of 15 bar, 150 metres, makes it an excellent everyday watch, one that you can keep on whatever you are doing, and the nylon strap also has no problems with water.

Dial

The dial is great. The hour markers look a bit like nautical burgees, and their design, blue appliqués with white SuperLuminova at the centre, is a nice touch, coordinating with the triangular faceted hour hand, and the triangles at the tips of the other three hands. The red-tipped GMT hand rotates once every 24 hours and shows the time in another time zone on the inner scale. The date window as usual causes something of a graphic design headache but they’ve camouflaged it quite effectively.

Movement

The movement is the self-winding Omega Master Co-Axial Calibre 8605. Two barrels (curiously labelled “barrel one” and “barrel two” on the movement bridge) provide 60 hours power reserve, which is good but not exceptional, in comparison (for example) with the Calibre SH21 by Christopher Ward, which has two barrels and attains a 120 hour power reserve, exactly double. The Omega Calibre 8605 runs at 25,200 vibrations per hour (3.5 Hertz), and it has a silicon balance spring that contributes to its excellent resistance to magnetic fields, up to 15,000 gauss. It is COSC-certified (maximum deviation -4/+6 seconds per day) but it doesn’t have the new Omega METAS certification.
