Promaster Marine 48 mm diver watch
This Citizen Eco-Drive Promaster Marine is a 48 mm men's diver watch built for serious ocean exploration. The substantial silver-tone stainless steel case measures 17.8 mm thick and pairs with a black rubber strap and pin buckle clasp. It is designed for marine sports and scuba diving.
Check wrist size and light exposure
The 48 mm case diameter and 17.8 mm thickness create a bold profile that may feel large on smaller wrists. The Eco-Drive J250 movement recharges from any light source, so regular exposure to light is needed to maintain the power reserve. Verify that the strap length suits your wrist before ordering.
Build quality and daily implications
A unidirectional rotating black stainless steel bezel surrounds the scratch-resistant mineral crystal protecting the black analogue dial. Luminescent hands, index hour markers, a date window at 3 o'clock and a power reserve indicator aid readability. The screw-down crown and solid case back support water resistance to 200 metres (660 feet).
