The latest model in the Aqua Terra line heralds a brand-new co-axial movement from the Biel/Bienne-based brand. The exclusive calibre 8605/8615 with a silicon balance spring is the first of the co-axial movements (which were introduced in 2007) to feature a GMT complication. Omega claims almost no need for lubrication of the co-axial movement thanks to reduced friction and backs this up with a four-year warranty.
Stainless-steel case, 43mm diameter, teak pattern dial, black leather strap with folding buckle. Water resistant to 150 metres.
