Full details

The Citizen Promaster NY0040-17L is a robust automatic diver's watch crafted for both professional underwater exploration and reliable daily wear. It is best suited for individuals who appreciate mechanical horology and high-visibility designs, offering the core advantage of a battery-free automatic movement paired with 200-meter water resistance; however, potential buyers should note that as a mechanical watch, it requires regular movement to keep accurate time if not worn daily.

Extended Product Information

FAQs

Does this watch require a battery?

No, this is an automatic watch that derives power from the movement of your wrist.

Can I wear this while scuba diving?

Yes, it is rated for 200 meters of water resistance, making it suitable for professional and recreational diving.

How do I wind the watch manually?

While it is automatic, you can also wind it by rotating the crown in the neutral position to manually build up the mainspring power.

What is the dial size?

The watch features a 42mm dial, providing a balanced presence on most wrist sizes.

How often should the watch be serviced?

It is recommended to have mechanical watches checked and lubricated by a professional every 3 to 5 years.

Is the strap replaceable?

Yes, the watch uses standard lugs that allow you to swap in different straps if desired.

Troubleshooting

Watch stopped running

The automatic movement needs energy; gently shake the watch for 30 seconds or wear it for a few hours to build up the power reserve.

Incorrect date change

Ensure you are not setting the date between 9 PM and 3 AM, as this is when the date-change gear is engaged and manually adjusting it could damage the movement.

Condensation under the crystal

This suggests a compromised seal. Stop using the watch in water immediately and consult an authorized Citizen service center.

Pros and Cons

No battery changes required due to automatic movement

Setup, Compatibility & Care

To set the time, pull the crown out to the second click and rotate it clockwise or counter-clockwise. For the day and date, pull the crown to the first click; rotating in one direction will adjust the date, and the other will adjust the day. To ensure the water resistance remains intact, always ensure the crown is fully screwed down before entering water. Clean the watch periodically with fresh water to remove salt or grit, especially after swimming in the ocean, and use a soft, dry cloth to wipe the case and strap.
