Design and Build Quality

The Casio F-B100W-1BDF combines classic digital watch aesthetics with modern materials and practical everyday comfort.

Inspired by Casio’s iconic 1980s digital watches, its angular case design and large LCD create a recognizable retro look while adding modern functionality.

Case and Digital Display Design

The watch features a resin case measuring 41.9 mm long, 38.1 mm wide, and 8.8 mm thick.

Its angular black case creates a distinctive appearance while maintaining a slim profile suitable for everyday wear.

The large digital LCD provides clear access to essential timekeeping information, including hours, minutes, seconds, PM indication, year, month, date, and day.

Unlike traditional basic digital watches, the F-B100W also displays additional information such as step counts and activity progress.

Its combination of classic design and multifunction display makes it a practical everyday timepiece.

The compatible band size ranges from 145 to 215 mm, accommodating different wrist sizes.

At just 26 grams, the watch feels lightweight despite its added technology and features.

Crystal and Water Resistance

Casio equips the F-B100W-1BDF with resin glass.

The watch also offers water resistance for everyday use, within Casio’s specified water-resistance guidance.

Casio does not assign a 30-metre or 50-metre water-resistance rating to this model.

Therefore, it should not be promoted as a swimming or diving watch.

For long-term care, avoid unnecessary water exposure and follow Casio’s recommended handling instructions.
