Seamaster Aqua Terra "Ultra Light"

55 grams and not a single gram more! This sports watch can thank Gamma Titanium for its ultra-lightness: an alloy used in the aeronautics industry for its low weight (less than conventional titanium) and great strength. As well as being sculpted from this high-tech material – and did we mention that the dial is also titanium - the 41mm case of the Seamaster Aqua Terra “Ultra Light” contains Omega's first ever in-house movement to incorporate a plate and bridges in ceramized titanium. This champion of precision has been awarded Master Chronometer certification by the Swiss Federal Institute of Metrology.
