What Stands Out

  • 44.4 mm case with large digits, readable without squinting or stopping what you are doing
  • 31 grams despite the size, because the case and band are all resin
  • Amber backlight and a seven-year battery estimate on the same CR2016 as the rest of the line
  • Band fits 145 to 215 mm, so it goes over a thick wrist or a jacket sleeve
  • 1/100 second stopwatch with split time for rest periods and intervals

What To Check

  • Resin glass scuffs more easily than mineral glass, so expect marks on a work watch
  • Casio lists it as Water Resistant with no meter rating, worth confirming before it goes near the lake
  • A 44.4 mm case is a lot of watch on a smaller wrist

The Casio F108WH-1A is the large, matte-black digital in Casio's cheap and cheerful line, and it sits inside the top 25 sellers in men's wrist watches on Amazon. The case runs 44.4 mm with a wide display, which is the one a dad can read at a glance with a kid on one arm and a leash in the other hand.

The backlight is amber, which is easier on the eyes in a dark room than a cold white LED. At 31 grams it is still light for its size, because the case, band and glass are all resin.

Safety and fit note. All resin, nothing to pinch or catch, which makes this the friendliest of Casio's vintage digitals around kids and dogs. Casio publishes no meter water-resistance rating on this model, so keep it to rain and splashes rather than swimming.

The Numbers That Matter

SpecWhat it decides
44.4 mm case, big digitsWhether you can read it without stopping
31 g all resinHow much watch you feel on a long day
About 7 years on CR2016How long before you think about it again
145 to 215 mm bandWhether it goes over a jacket sleeve

The display. This is the whole reason to pick it. Casio gave the F108WH a wide face and tall digits, so a glance is enough while your hands are full.

The weight. 31 grams on a 44.4 mm case is the trade for all-resin construction. You get size without heft, at the cost of a crystal that scuffs.

The band range. 145 to 215 mm is the widest in this group, which means it fits over a thicker wrist or a jacket cuff in December.

Who It Is For

The dad who wants a big, plain, readable watch for work, the yard and the ball field. For the small, light version of the same idea, see the Casio F91W-1. If you want steel instead of resin, look at the Casio A158WA-1 or the larger Casio A168WA-1. For a rated 100 meter digital that swims, the Casio W800H is the one, and the Timex Ironman Classic 30 covers five-button training features.

The Short Version

This is the big-digit, all-black option in the vintage Casio line. I would point a dad here who wants to read the time at a glance with a kid on one arm and a leash in the other. If you want something smaller and dressier, the Casio A158WA-1 is the steel one.
