Tool-Watches family for exceptional lives
OX® FROG300 tool-watches are designed and engineered for professional use and built for those who live beyond limits.
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-watch line features an independent dual-time-zone, true GMT complication, designed for ocean and land explorers far from their loved ones. This family is powered by the acclaimed, customized Miyota 9075 automatic caliber, individually regulated for timekeeping accuracy, approaching COSC standards.
The PRO line is a three-hand version focused on delivering fully intuitive, immediate legibility. It shares the same G3i titanium case as the GMT family, but features an internal unidirectional bezel and a purpose-designed dial engineered for fast, unmistakable reading in the most demanding working environments. It is the perfect companion for today’s modern professional diver.
