Tool-Watches family for exceptional lives
The FROG300 was designed around use, not around conventional watch architecture.
Its eccentric 45 mm Grade 3i titanium case places both crowns on the inner side, away from the hand. WR300M / 1000FT, an internal unidirectional Dive Time bezel, 4 Hz automatic mechanics and ID+SYS™ come together in one unmistakable architecture.
Function comes first. Form responds.
BUILT OTHERWISE.
A DIFFERENT WAY TO BUILD A TOOL WATCH.
ON THE OX® FROG300 THE CROWNS ARE ON THE WRONG SIDE.
ON PURPOSE.
Both crowns of the FROG300 sit on the inner side of the case.
That architecture was conceived for the watch to be worn on the left wrist, keeping the crowns away from the hand and leaving it free to move.
It looks unconventional because it is unconventional.
But different only matters when there is a reason for it.

DESIGNED FROM SCRATCH.
DOWN TO THE LAST SCREW.
With an OX®, even the smallest components matter.
Specific case, clasp and construction elements are designed from scratch rather than adapted from standard catalog solutions.
The mechanical calibers are the exception. But even there, we leave our mark: each one is customized and individually regulated by OX®.
The value should be in the watch. Not in the rhetoric.
ONE FROG300. TWO WAYS TO USE IT.
MORE THAN ONE TIME ZONE.
For travel, exploration and a life that does not necessarily stay in one place.
The FROG300 GMT adds a True GMT complication to the core FROG300 architecture, powered by the customized premium MIYOTA® 9075M automatic 4 Hz caliber.
Local time can be adjusted independently while the second time zone remains exactly where you need it.
True GMT. Dive Time. ID+SYS™.
THREE HANDS. IMMEDIATE READING.
PRO takes the same FROG300 architecture in the opposite direction: less information, maximum clarity.
Powered by the customized premium MIYOTA® 9015M automatic 4 Hz caliber, its three-hand display was conceived for immediate, intuitive reading in diving and maritime environments.
Nothing unnecessary. Nothing gets in the way.

ID+SYS™. ESSENTIAL INFORMATION, INSIDE YOUR WATCH.
Every FROG300 carries it.
We developed ID+SYS™ to make essential personal and emergency information easier for rescue teams to access when it may matter most. No battery. No Wi-Fi connection. Protected inside the watch. The OX® FROG300 was designed to help save your life. We hope that day never comes.
