A unisex digital chronograph for daily timing

The Casio B650WB-1B is a quartz-powered watch with a rectangular resin case and a black digital display. It combines chronograph, alarm and day-date functions in a single unisex design. The LED backlight with afterglow keeps the screen readable in low light.

Resin case on a stainless-steel bracelet

The 43.10 mm resin case pairs with a black IP stainless-steel band that fastens via a deployment clasp. A fixed bezel and resin crystal protect the module. No additional tools or adapters are required to wear it.

Water-resistant to 50 m with no charging needed

The quartz movement runs from a battery, so there is no daily charging routine. Water resistance rated to 50 m handles splashes and brief immersion. The resin construction keeps weight low and the watch silent in normal use.

Questions about this item

How long does the LED backlight afterglow stay visible after the button is released?

The LED backlight afterglow remains lit for a short period after the button is released, providing enough time to read the digital display in darkness.

Does the resin case and stainless steel bracelet become hot during continuous wear in direct sunlight?

The resin case and stainless steel bracelet may warm up slightly in direct sunlight but do not become uncomfortably hot during normal all-day wear.

Is any tool required to adjust the deployment clasp on the stainless steel bracelet?

The deployment clasp features a push-button release for easy opening, while link adjustment on the bracelet typically requires a standard spring-bar tool.
