Dressed in a 42.2mm diameter stainless steel case, this Seamaster Aqua Terra Chronograph watch comes with a black or white dial.
The Seamaster Aqua Terra Big−size Chronograph is equipped with the Omega 3301, a self-winding column wheel chronograph movement based on the Piguet 1285 calibre. Certified as official chronometer, it provides a power reserve of 55 hours. The Cal. 3301 is equipped with 33 jewels and it beats at the rate of 28,800 vibrations per hour.
Its dial features three counters: the chronograph 30 minute register at 3 o’ clock, the chronograph 12 hour register at 6 o’ clock and the small seconds at 9 o’ clock. It has three centre hands: a dauphine hand for the hour, an arrow-shaped hand for minute and a spear-shaped hand for chronograph seconds. All the three hands employ luminescent coating. The dial also spotlights a date window at 6 o’ clock.
The models with a white dial feature blue hands and index hour markers. The black dial variants come with silver-toned hands and indexes.
Water resistant to 150 meters, the Omega Seamaster Aqua Terra Big−size Chronograph is available with a three-links stainless steel bracelet or alligator leather strap.
