Seamaster 300.
Co-axial Master Chronometer, 41 mm.

Bronze gold on leather strap.

In 1957, Omega first launched the Seamaster 300, specifically designed for divers and all professionals who work underwater. After more than sixty years, the collection has been completely renewed and now includes this special model created in the brand's bronze alloy.

The 41 mm case and bezel are made of 9 kt bronze gold, while the brown ceramic bezel ring features a graduated scale with a Super-LumiNova insert. The bronze-coloured dial features sunken hour markers and numerals with Super-LumiNova inserts, as well as golden bronze PVD hands.

Equipped with a brown leather strap with a 9 kt bronze gold buckle, the watch has a transparent sapphire crystal case back that allows a view of the OMEGA Co-Axial Master Chronometer calibre 8912.

Exposure to strong magnetic fields, even those of over 1.5 tesla (15,000 gauss), does not affect the movement.

Master Chronometer certificate.
This certificate guarantees one of the highest standards of precision, performance and magnetic resistance in the Swiss watchmaking industry, as established by the Swiss Federal Institute of Metrology (METAS).

Screw-down crown.
Self-locking crown screwed to the case, used in water-resistant diver's watches.

The watch has passed specific tests for precision and has received a certificate issued by an official institution (COSC).

Transparent case back.
The transparent case back, made of thick sapphire crystal, allows you to see the movement inside the watch.

Unidirectional rotating bezel.
The bezel can be rotated in one direction only. Particularly useful for divers, as it cannot be accidentally rotated the opposite way, causing an error in the calculation of diving times. The rotating bezel helps measure the time passed.
