The GOA has a diameter of only 48mm and a high contrast display of 35mm. It is a scuba diving/apnea watch-computer of extremely reduced dimensions. It is also an ideal watch for other underwater activities, thanks to the deactivation option of the “dive” functions that avoids unnecessary alarms ringing while you’re snorkelling or swimming.
The display is made of mineral glass and the case is heavy duty with steel buttons that have an underwater resistance of up to 120m.
Rubber wrist band with stainless steel buckle.
Plastic/Steel bezel and back cover
Anti-impact technopolymer case.This composition allows a great lightness, resistance to the blows and to the aesthetic aging. The computer case is extremely flat, with a very hydrodynamic cornerless section and its dimensions are relatively contained, with a vision of the model digits.
Extra-flat profile(maximum height 14 mm) with a completely rounded design, very hydrodynamic and avoids possible snagging. Even the anchorage of the strap follows the profile of the box.
Two highly integrated low-profilepushbuttons with the minimised backlash to ensure that the O-rings are watertight when working perfectly perpendicularly and to prevent the entry of particles or small grains of sand that could block them.
Case diameter only 48 mm
Large screen UFDS (User-Friendly Display System)38 mm in diameter vs 48 mm total box. The distribution of the information, screen contrast, proportions and size of the digits have been studied to facilitate the reading. All data are segmented with slight separation lines that facilitate reading even in a stressful or emergency situation.
New high-performance, low-power processor. Allows much faster data processing, more power backlighting and sound alarms and doubles the battery life compared to previous models. CPU ARM Cortex M3 32 bit | Frequency14 MHz | Flash Memory 256 Kb | 32 Kb RAM
High intensity backlitdisplayby push-button or in case of alarm (5 seconds per push)
High-strength mineral crystal display
Guaranteed resistance up to 120 m depth
Optional Bluetooth interface
