Omega Aqua Terra 150M Master Co-Axial Chronometer Ladies’ 38.5 mm White Dial (231.20.39.21.55.003)

Description

Equipped with one of the world’s most advanced mechanical movement, the Seamaster Aqua Terra Master Co-Axial is stylish, sporty and prepared for an active lifestyle. This luxurious model features a pearled mother-of-pearl dial with 11 diamond indexes in 18K gold holders.

This 38.5 mm 18K red gold and stainless steel ladies’ wristwatch is presented on a stainless steel bracelet with 18K red gold links. At its heart is the revolutionary OMEGA Master Co-Axial calibre 8500, a movement that can resist strong magnetic fields – even those greater than 15,000 gauss.

• Chronometer

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

• Date

  The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o’clock.

• Diamonds

  The hardest, most luminous precious stone whose value is calculated according to the 4C criteria: Cut – Carat – Clarity – Color.

• 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.
