Diver 300M Co‑Axial GMT Chronograph 44 mm
Steel on steel
OMEGA’s sporty Seamaster collection is a tribute to the brand’s maritime legacy. This exquisite example of our renowned watchmaking pays homage to OMEGA’s dive watch heritage and our adventurous pioneering spirit.
This OMEGA Seamaster Diver 300M GMT Chronograph features a matt blue dial with 30-minute and 12-hour recorders and a small seconds sub-dial. There is a yellow GMT hand that matches the yellow 24-hour scale on the dial which makes it possible to keep track of time in a second time zone. The matt blue ceramic unidirectional rotating bezel is mounted on a 44 mm stainless steel case with a helium-escape valve.
The watch is presented on a stainless steel bracelet. This chronograph is powered by the OMEGA Co-Axial calibre 3603.
All OMEGA watches are delivered with a 5-year warranty that covers the repair of any material or manufacturing defects. Please refer to the operating instructions for specific information about the warranty conditions and restrictions.
