Aqua Terra 150M Co-Axial Master Chronometer 41mm

Description

Built for sporting comfort, the ergonomically designed "Ultra Light" is fashioned from an alloy called Gamma Titanium, a strong yet lightweight material used in the aeronautical industry. The use of Gamma Titanium is a first for OMEGA. As is the telescopic crown, which can be stowed inside the case when not in use.

Presented on a black rubber strap, the watch includes a sandblasted grade 5 titanium dial featuring the iconic Aqua Terra stripes. When worn on the additional sporty fabric strap, the watch weighs just 55 grams.

This 41 mm Aqua Terra makes bold use of red on the aluminium seconds hand, Seamaster logo, quarter hour markers and strap stitching. The watch is powered by the OMEGA Co-Axial Master Chronometer Calibre 8928 Ti, the brand's first movement built from titanium.

Features

• Anti‑magnetic

  The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).

• Chronometer

  Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).

• Master Chronometer Certified

  Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology (METAS).

• Screw‑in crown

  Self-locking crown, screwed into the tube of the case, used for highly water resistant divers' watches.

• Time zone function

  Allows the hour hand to be easily adjusted to different time zones without stopping the watch.

• Transparent case back

  A transparent case back - frequently made of sapphire - makes it possible to see the movement inside the watch.
