Diver's Watch with 200 m Water Resistance

The Citizen Promaster Eco-Drive Orca is a men's diver's watch built for underwater use and daily wear. Its ISO-compliant 200 m rating supports serious recreational diving, not just splash protection. The unidirectional rotating bezel allows elapsed-time tracking during a dive. Solar-powered Eco-Drive movement removes the need for battery changes.

Stainless Steel Case and Polyurethane Strap

The 46.00 mm stainless steel case features a screw-down crown that secures the seal against water ingress. Mineral crystal covers the black analog dial with index markers and a date window at three o'clock. A polyurethane strap with buckle clasp resists salt water and stays flexible in cold conditions. The case back carries the caliber E168 designation.

Solar Power and Depth Limits

Eco-Drive converts any light source into electrical energy, so the watch runs continuously without opening the case. The 200 m limit defines the maximum pressure the seals are tested to withstand; exceeding it risks water entry. The unidirectional bezel prevents accidental addition of dive time, a safety requirement for the diver's classification. No computer synchronization or smart notifications are included.

Questions about this item

What depth rating does the 200M diver rating on this Citizen Promaster Eco-Drive Orca cover in practice?

The 200-metre water resistance rating means the watch is suitable for professional marine activity and serious surface water sports, including recreational scuba diving to that depth.

What case diameter and lug arrangement does the 46.00 mm stainless steel case need to fit a wrist?

The case measures 46.00 mm in diameter and uses standard spring bars between the lugs to accept the supplied polyurethane strap with buckle clasp.

How is the Eco-Drive E168 movement charged, and what step do owners often miss?

Expose the black dial to any light source — natural or artificial — to charge the solar cell; the common mistake is storing the watch in darkness long enough for the power reserve to deplete.
