Omega Seamaster Aqua Terra 150M GoodPlanet GMT 43mm 231.92.43.22.04.001 with white dial and blue highlights. The case is in titanium, 43mm in diameter, and quite chunky at 14.15 mm thickness. It is mainly brushed, with polished details and bezel. The water resistance of 150 m, makes it an excellent everyday watch and the nylon strap also has no problems with water.
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.
