SKU CH-NJBR-SS8BS

A lightweight digital sport watch with 50 m water resistance, 1/100-second stopwatch, countdown timer and LED backlight

  • 50 m water resistance handles splashes and brief immersion
  • 1/100-second stopwatch plus 24-hour countdown timer for precise timing

Everyday digital watch for active routines

The Casio LW-204-1BCF is a lightweight quartz watch built for daily wear and sport timing. Its resin case and band weigh 24 grams and measure 38.9 × 35 × 9.4 mm, so it stays comfortable during extended use. The all-black finish suits both casual and fitness settings. Buyers needing a metal bracelet or smartwatch connectivity should look elsewhere.

Stopwatch precision and 50 m water resistance

The 1/100-second stopwatch handles interval training and lap timing with fine granularity. A 24-hour countdown timer supports long-duration events, while five multi-function alarms and an hourly signal keep schedules on track. Water resistance to 50 meters covers splashes, rain and brief immersion, but not swimming laps or diving. The CR2016 cell lasts about three years before replacement.

Compact strap design fits small wrists

The 21 mm band width and short case length suit narrower wrists without overhang. Resin construction resists sweat and cleans easily after workouts. LED backlight with afterglow and flash alert deliver readable alerts in dim light without a button press. No heart-rate sensor, GPS or phone notifications are included, so users wanting health tracking will need a dedicated device.

Questions about this item

Will the 38.9 × 35 × 9.4 mm case fit comfortably alongside a traditional metal bracelet watch?

The compact resin case is only 9.4 mm thick and weighs 24 grams, so it sits flat and light on the wrist without clashing with a heavier metal watch worn on the other arm.

How can I confirm the 1/100-second stopwatch and countdown timer are functioning correctly after setup?

Start the stopwatch and verify the display increments in hundredths of a second; set the countdown timer for a short period and check that it reaches zero with the flash alert and buzzer sounding.

Does the package include the CR2016 battery and the resin strap, or must either be purchased separately?

The watch ships new with the CR2016 battery already installed and the black resin strap fitted to the 21 mm lug width, so no separate purchase is required.
