Compact GMT for daily travel

The Citizen Promaster Land GMT fits a 39.5 mm stainless steel case rated to 200 meters water resistance. Solar powered Eco Drive movement runs on light and stores energy for approximately nine months on a full charge. A black dial with 24 hour scale and dedicated dual time display tracks two zones at once.

Solar power removes battery changes

The B878 caliber charges from any light source and includes a low charge warning for dependable operation on long trips. No battery replacements are required, so the watch stays ready across time zones. A date display keeps your itinerary on schedule without extra adjustments.

Sapphire crystal and screw down crown

A tough sapphire crystal with anti reflective treatment improves legibility in bright conditions. The screw down crown and case back maintain the 200 meter seal during swimming or diving. Stainless steel bracelet with fold over push button clasp secures the piece comfortably on the wrist.

Questions about this item

How long does the Eco-Drive power reserve last when the BJ7150-50E is kept in darkness?

The B878 solar calibre stores enough energy for approximately 9 months on a full charge, and a low-charge warning alerts you before the watch stops.

What component limits continuous dive use on the Promaster GMT?

The 200 m water-resistance rating and screw-down crown define the depth limit; the fixed bezel does not track elapsed time, so a separate timer is needed for decompression stops.

Does the stainless steel bracelet or sapphire crystal generate noticeable heat during all-day wear?

The watch is light-powered with no active electronics, so it produces no perceptible heat; the bracelet and crystal remain at skin temperature throughout the day.
