Casio F-B100W-1AEF men's digital watch from the Timeless Collection

Not every watch needs to shout for attention. The Casio F-B100W-1AEF is a rectangular digital watch for men that keeps things practical without looking dull, thanks to a black resin case with a blue trim running around the LCD display and silver-coloured buttons that give it a clean, sporty edge. It belongs to Casio's Timeless Collection, a line built around the idea that a watch should simply do its job day after day. If you want something reliable on your wrist without committing to a full smartwatch, this is worth a closer look.

Inside, Casio fitted the F-B100W-1AEF with a quartz movement, specifically the Casio Module 3589, paired with Bluetooth connectivity so you can sync the time and activity data straight to your phone. There is also a built-in step tracker, which means you can keep an eye on your daily movement without strapping a separate fitness device to your other wrist. The case measures 41.9 × 38.1 × 8.8 mm, compact and slim enough to sit comfortably under a cuff, and the whole thing is made from resin, so it stays light even on long days. The strap is made from bio-based resin, a small but considered material choice that takes a step away from purely synthetic construction. Daily life water resistance covers you through rain, hand washing and the occasional splash at the kitchen sink, though this is not a watch you would take swimming.
