CASIO LQ-139B-1B 25 mm Analog Watch

Compact 25 mm analog watch for daily wear

The Casio LQ-139B-1B is a classic analog watch with a 25 mm round case made of stainless steel and black resin. A quartz movement drives black Arabic numerals and hands on a white dial behind a resin glass window. The matching black resin band fastens with a traditional buckle. It is designed for adult wear in black.

Check band fit and water needs before ordering

The 25 mm case size is compact, so verify it suits the intended wrist. Water resistance handles minor splashes but is not rated for swimming or bathing. The resin band uses a standard buckle closure; no tool-free adjustment is mentioned. Ensure the simple analog display meets the required readability.

Quartz movement runs cool

Quartz operation produces no audible noise and negligible heat during normal use. A single button cell powers the movement for extended periods without user intervention. The resin case and glass window add no active cooling requirements. Routine exposure to splashes does not affect thermal or electrical performance.
