This automatic Promaster Dive watch pairs iconic diver styling with practical performance. The sapphire crystal shields a deep blue sunray dial framed by a bold rotating bezel for easy elapsed time tracking. Its automatic movement charges through wrist motion, giving about 42 hours of reserve and eliminating battery needs. A black accordion-style polyurethane strap adapts comfortably to wrist size and wetsuit use, while ISO‑rated 200 meter water resistance and a screw-down crown ensure rugged reliability whether underwater or on dry land.
