Vintage calculator watch

The Casio CA-500WEGG-9B is a unisex digital watch with an integrated 8-digit calculator. Its rectangular resin case measures 34.40 mm in thickness and pairs a black-and-yellow dial with a gold-tone stainless steel bracelet. Quartz movement powers the timekeeping and date functions for everyday casual wear.

Built-in calculator and deployment clasp

The calculator handles basic arithmetic directly on the wrist, removing the need for a separate device during quick tasks. A deployment clasp secures the stainless steel band with one-handed operation, while the resin crystal protects the digital display from daily knocks.

Splash-resistant quartz limits

The watch is rated splash resistant only, so it must not be submerged or worn while swimming. Quartz accuracy depends on a single button cell that will require periodic replacement. The fixed bezel and 34.40 mm case thickness restrict strap interchangeability to the supplied bracelet.

Questions about this item

How often will the battery need replacing on the Casio CA-500WEGG-9B calculator watch?

Quartz movement with an 8-digit calculator typically runs several years on a single cell; exact interval depends on how often the calculator and backlight are used.

What limits continuous use of the 8-digit calculator on this watch?

The 8-digit display caps the size of numbers you can enter or view; beyond that the quartz module itself has no thermal or power throttle.

Does the Casio CA-500WEGG-9B get warm or make noise when worn all day?

Quartz modules are silent and produce no noticeable heat; the resin case and stainless steel band stay at skin temperature during all-day wear.
