Citizen Promaster BN1024-01Z Diver's Watch

The Citizen Promaster BN1024-01Z is a 300-meter water-resistant diver's watch built for underwater exploration and adventure. Its Eco-Drive movement converts light into energy, removing the requirement for battery changes. A 46.00 mm stainless steel case houses a red analog dial with index and dotted markers. The polyurethane strap and buckle clasp secure the watch during active use.

Thermals Noise Power

Eco-Drive technology harvests ambient and artificial light to charge the internal power cell continuously. No battery replacements are needed, eliminating the waste and hassle of periodic servicing. The sealed screw-down crown and case back maintain 300M water resistance without user intervention. Operation stays silent and temperature-neutral on the wrist.

Build Fit Requirements

A unidirectional rotating bezel allows elapsed-time tracking for dive planning without additional instruments. Sapphire crystal protects the dial from scratches during rugged outdoor activity. The 46.00 mm case diameter suits larger wrists but may overwhelm smaller frames. Buyers needing a metal bracelet or integrated GPS functionality should consider other models.

Questions about this item

How do I set the time and date on the BN1024-01Z, and what step is often missed?

Pull the screw-down crown to the first click for the date, then to the second click for the time; the step often missed is screwing the crown back down fully to maintain the 300M water resistance.

What part of the BN1024-01Z will need replacement after several years of daily wear?

The polyurethane strap will eventually show wear and require replacement, while the Eco-Drive cell and sapphire crystal are built for long-term service.

At what depth does the BN1024-01Z reach its rated limit during a long dive?

The watch is rated to 300M, so that depth is the limit where the screw-down crown and case seals are tested to their maximum specification.
