Mechanical Diver Watch Citizen Promaster NY0145-86E — Automatic, 200m Water Resistance, Stainless Steel Case, 42mm

Citizen Promaster Mechanical Diver NY0145-86E is an automatic wristwatch engineered for recreational diving and everyday wear. The watch combines a 42mm stainless steel case with a unidirectional bezel, screw-down crown and luminous hands and markers to ensure legibility and water resistance to 200 meters. Its mechanical automatic movement winds from wrist motion, providing continuous operation without a battery while retaining the durability expected from a dive-oriented tool watch.

Advantages

The stainless steel case and solid construction deliver long-term wear resistance while the 200m water resistance and screw-down crown protect the movement during underwater activities. A unidirectional bezel offers a reliable elapsed-time function for dive timing, and luminous hands and markers improve visibility in low-light conditions. The automatic winding movement reduces the need for battery changes and supports sustained operation through daily use and active lifestyles.

Suitable for

• Recreational scuba diving and snorkeling
• Water sports such as swimming and sailing
• Daily wear in outdoor and indoor environments
• Users who prefer mechanical automatic watches over quartz models

Key specifications

• Case material: stainless steel
• Case diameter: 42 mm
• Movement type: automatic mechanical movement (self-winding)
• Water resistance: 200 meters (suitable for diving)
• Bezel: unidirectional rotating bezel for elapsed time tracking
• Crown: screw-down crown for enhanced water protection
• Dial features: luminous hands and hour markers for low-light legibility

How to use

Wear the watch on the wrist so the rotor can wind the movement through natural arm motion; regular daily wear typically keeps the mainspring charged. Before submerging, ensure the screw-down crown is fully tightened to maintain the specified water resistance. Use the unidirectional bezel to measure elapsed dive or activity time by aligning the bezel zero marker with the minute hand. For time setting, gently unscrew the crown, pull to the appropriate position to set time and date if applicable, then push and screw the crown back to secure it.

Usage recommendations

To preserve water resistance, have the seals and crown checked during periodic maintenance and after any hard impacts or prolonged exposure to salt water; rinse the watch in fresh water after saltwater exposure. Service the mechanical movement according to manufacturer's guidelines or when timekeeping performance noticeably changes.
