Classic colour. Nothing else is.

OXF3-BKBKTI-BLACK

BLACK EDITION

Black is probably the most traditional colour a tool watch can wear.


That is exactly where tradition ends.

The OX® FROG300 GMT Black Edition combines the understated character of black with everything that makes a FROG300 unmistakably different: its eccentric titanium architecture, True GMT automatic movement, underwater-adjustable internal dive bezel and ID+SYS™ emergency data system.

 

Built in Grade 3i Titanium, water-resistant to 300 metres / 1,000 ft, and designed for exceptional comfort despite its 45 mm case, it is a professional tool watch made to be worn far beyond the water.

 

Timeless on the outside. Built Otherwise underneath.

All-Terrain Pro Diver’s¹ it is.

1 FROG300 BLACK EDITION, THE MOST CLASSIC FROG300. ONLY IN COLOUR.

THREE ESSENTIAL FUNCTIONS. ONE VERY DIFFERENT ALL-TERRAIN TOOL WATCH.

 

A premium MIYOTA® 9075 True GMT automatic calibre with independent jumping local hours. An internal unidirectional Dive Time bezel that can be adjusted underwater. And ID+SYS™, OX®’s always-available emergency data system.

Three genuinely useful functions, built into the unmistakable architecture of the FROG300.

DETAILS WITH A PURPOSE.

Even the luminous FROG signature on the side of the 45 mm case is more than a visual detail. Together with the dial and Dive Time bezel, it uses high-grade Super-LumiNova® W9/X1 for clear identification and readability in low-light conditions.

 

Different by design. Useful by instinct.

DO SOMETHING GREAT. REACH FURTHER!

An extraordinary life demands a companion that can keep up.

On land or underwater, the FROG300 combines three essential functions, exceptionally robust construction, and the reliability to go wherever you choose to take it.

BUILT TO GO WITH YOU.

Ti G3i  ISO  DIVER’S WR1000FT AUTO GMT ID+SYS™

On the right side of the 45 mm case, you’ll find the FROG signature in low relief. A detail that completes the design of that area, but also serves a purpose. Its powerful applied lume can even act as a mini emergency flashlight in zero-light conditions.

The luminescence of the OX® FROG300 is Grade W9/X1 applied filled in two-tone to differentiate between dive time and hour. The Black Edition model uses green and blue colors.
