Tool-Watches family for professionals
OX® FROG300 tool-watches are designed for professional use and built for exceptional lives.
Produced in limited numbers, each piece reflects a deliberate and uncompromising approach to tool-watch design.
They are crafted using premium materials and a unique, unconventional architecture, where the crowns are positioned inward within an eccentric case design.
This innovative layout delivers unprecedented comfort for a 45mm professional tool-watch, even in the most demanding conditions.
The OX® FROG300 family is available in two lines, both featuring automatic premium 4Hz calibers and integrated with ID+SYS™ data technology :
The GMT tool-watches line, featuring an independent dual time zone, and the PRO line, a three-hand version focused on delivering fully intuitive and direct legibility.
