Citizen Men's Promaster Sea Aqualand Eco-Drive Watch, Polyurethane Strap, Chronograph, Date, 12/24 Hour Time, Power Reserve Indicator, Sapphire Crystal, Luminous Hands and Markers

Items Description

The Citizen Men's Promaster Sea Aqualand Eco-Drive Watch is a professional-grade dive chronograph built for underwater exploration and rugged daily wear. Powered by Citizen's Eco-Drive technology, this timepiece converts light into energy, eliminating the need for battery replacements. Designed for scuba divers, snorkelers, and outdoor enthusiasts, it combines a full-function chronograph with a dedicated depth meter, delivering reliable performance in demanding aquatic environments.

 

Housed in a stainless steel case with a black polyurethane strap, this Aqualand model balances durability with comfort. The polyurethane strap resists saltwater, UV exposure, and flex fatigue, while the sapphire crystal offers superior scratch resistance. A luminous dial with coated hands and markers ensures readability in low-light conditions, and the power reserve indicator keeps the wearer informed of remaining charge. From tropical reefs to overcast skies, this watch is engineered to perform.

 

Key Advantages of the Citizen Men's Promaster Sea Aqualand Eco-Drive Watch, Polyurethane Strap, Chronograph, Date, 12/24 Hour Time, Power Reserve Indicator, Sapphire Crystal, Luminous Hands and Markers

 

1. Professional Dive Functions with Depth Meter

As part of the Promaster Sea collection, this Aqualand model includes a dedicated electronic depth sensor that measures water depth down to 70 meters. The depth display updates in real time, with an auto-start dive mode that begins recording as soon as the watch enters water. A maximum depth memory function logs the deepest point of each dive for post-dive review.

 

• Depth Display: Shows current depth down to 70 meters in one-meter increments.
• Auto-Start Dive Mode: Activates automatically upon submersion, tracking elapsed dive time.
• Maximum Depth Memory: Stores the deepest depth reached during a dive for later reference.
• Rapid Ascent Alarm: Alerts the diver when ascent speed exceeds safe limits.

 

2. Eco-Drive Solar Charging System

The watch runs on Citizen's Eco-Drive movement, which converts light from any source—natural or artificial—into electrical energy stored in a lithium-ion cell. This eliminates the need for periodic battery changes and allows the watch to run continuously for months on a full charge. The power reserve indicator on the dial shows remaining charge at a glance.

 

• No Battery Changes: Powered entirely by light, with no regular service required.
• Power Reserve Indicator: Visual display of stored energy levels on the dial.
• Charging Flexibility: Works under sunlight, indoor lighting, or even low-level ambient light.
• 6-Month Reserve: Holds a charge for extended periods in darkness after full exposure.

 

3. Chronograph and Multi-Function Display

Beyond dive instrumentation, the Aqualand includes a 1-second chronograph capable of measuring elapsed time up to 50 minutes. This functions as a stopwatch for surface intervals, timing drills, or general timing tasks. The watch also features a 12/24-hour time display option and a calendar date window at the 3 o'clock position.

 

• Chronograph: 1-second resolution with up to 50-minute timing capacity.
• 12/24-Hour Format: Switch between standard and military time display.
• Date Window: Calendar function positioned for quick readability.
• Dual-Purpose Layout: Digital sub-dials complement the analog main display for complex data readouts.

 

4. Sapphire Crystal and Luminous Readability

Protecting the dial is a sapphire crystal, one of the hardest transparent materials used in watchmaking. It resists scratches from sand, coral, or accidental impacts. The dial's luminous hands and markers employ a photoluminescent coating that absorbs light and glows in darkness, ensuring legibility during night dives or in low-illumination environments.

 

• Sapphire Crystal: High hardness rating, resistant to scratches and abrasion.
• Luminous Coating: Bright, long-lasting glow applied to hands and hour markers.
• Anti-Reflective Treatment: Reduces glare for clear viewing underwater or in bright sunlight.
• Enhanced Contrast: Black dial with white and accent-colored markings for high legibility.

 

5. Durable Stainless Steel Case and Polyurethane Strap

The 53 mm stainless steel case features a two-tone finish with Diamond-Like Carbon (DLC) coating on the bezel, enhancing abrasion resistance against rock and metal surfaces. The black polyurethane strap is flexible, lightweight, and resistant to seawater degradation, holding up under repeated wet and dry cycles. The screw-down crown and case back ensure water integrity.

 

• DLC-Coated Bezel: Hardened surface reduces wear from impact and friction.
• Water Resistance: Rated to 200 meters, suitable for professional scuba diving.
• Polyurethane Strap: Non-corrosive, UV-stable material with a secure buckle closure.
• Lug Width: 22 mm strap opening for potential aftermarket strap compatibility.

 

The Citizen Men's Promaster Sea Aqualand Eco-Drive Watch is best suited for certified divers and frequent snorkelers who need reliable depth tracking and chronograph functionality in a single instrument. For daily wearers or fitness swimmers who prioritize a straightforward dive watch without digital sub-dials, this model's depth sensor may be more than required—but its robust construction, solar charging, and scratch-proof crystal offer lasting value beyond the water.
