The GOA has a diameter of only 48 mm and a high contrast display of 35 mm. 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 snorkeling 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.
