Citizen Promaster Diver Solar Watch

The Citizen Promaster Diver BJ8057-17X is a solar-powered analog watch built for professional diving. A stainless-steel case and mineral crystal protect the green dial with index markers. Water resistance reaches 300 metres and a unidirectional rotating bezel tracks elapsed time. The rubber strap uses a buckle clasp for secure wear.

Suited for divers and daily wearers needing 300m

This watch fits buyers who want a solar movement that charges from any light source and a screw-down crown for water integrity. It is not for buyers who require a bracelet instead of a rubber strap or a sapphire crystal. The 48.50 mm case thickness may not suit wrists that prefer a slimmer profile.

Eco-Drive B873 movement sustains operation without

Under continuous use the solar cell recharges the power reserve from ambient light, so the watch keeps running during extended trips. The analog display and date window remain legible at depth. No winding or external charging is needed for normal daily activity.

Questions about this item

What case diameter does the BJ8057-17X have so I can check strap fit?

The case measures 48.50 mm across, so any replacement strap must suit that lug width.

Will the solar B873 movement keep running if I wear the watch only on weekends?

Light charges the Eco-Drive cell; regular indoor or outdoor exposure tops it up, and the power reserve covers periods when the watch stays in a drawer.

How can I verify the 300 m water resistance is still intact after I fit the extra rubber strap?

A professional pressure test at a watchmaker confirms the screw-down crown and case back seal hold the rated depth.
