Retro digital watch for everyday styling

The Casio B640WC is a unisex quartz watch with a rectangular resin case and a stainless-steel bracelet finished in a warm gold tone. Its digital display shows the time and date at a glance. A Super Illuminator LED backlight provides clear visibility in low-light conditions. The lightweight construction makes it suitable for all-day wear.

Check strap fit and display preference

The bracelet uses a deployment clasp on a fixed-bezel case measuring 38.90 mm in thickness. Ensure the clasp style and case profile suit your wrist before ordering. The mineral crystal protects the digital module, so verify you prefer a digital readout rather than an analogue dial. No additional tools or sizing links are mentioned in the specifications.

Bundled functions support daily routine

The watch includes standard timekeeping, date display and the Super Illuminator backlight as its core features. These functions cover basic scheduling and night-time readability without requiring a smartphone connection. No extra sensors, apps or charging accessories are supplied, so the experience remains focused on simple, reliable operation.

Questions about this item

What comes in the box with the B640WC and is anything else needed to start using it?

The watch ships ready to wear with its stainless-steel bracelet and deployment clasp already fitted; the quartz movement runs on the pre-installed battery so no separate purchase is required.

The case is listed as 38.90 mm — how do I decide if that size suits my wrist?

At 38.90 mm the rectangular case sits compact on most wrists; the lightweight resin case and adjustable stainless-steel bracelet let you fine-tune the fit without tools.

What does the Super Illuminator LED backlight actually do on this model?

Press the light button and the LED floods the digital dial with bright, even illumination so the time, date and any active function remain readable in complete darkness.
