The Casio F-108WH-1ACF Illuminator is a black resin digital Casio built for everyday wear. It keeps the familiar Casio button layout, adds an Illuminator backlight, and sits in the same budget resin lane as the classic Casio F-91W. If you want a slightly larger face with a brighter night light than the F-91W, this is the model that sits next to it on Amazon.
At the time of writing, Amazon.com had the F-108WH-1ACF for $20.97, with a list price of $29.95 shown, shipped and sold by Amazon.com and in stock, as checked Nov 2, 2026 at about 9.55pm Manila. Confirm the seller and the exact SKU before you check out.

The Specs That Matter
- Casio lists the F-108WH as water resistant, with no meter or BAR figure on the official product page. Casio’s water resistance FAQ treats unmarked Water Resistant as rain and hand washing only, with swimming off the table. Amazon’s listing contradicts itself with a 100M claim in one place and a 30M claim in another. The Casio spec is the one to trust, and the F-108WH is no 100M dive watch.
- Casio case size for the F-108WH is 44.4 mm high, 42.6 mm wide and 10.3 mm deep, with a stated weight of 31 g.
- Amazon’s measurements table lists a case diameter of 42.4 mm and a case thickness of 10.26 mm. Those Amazon-only figures sit close to Casio’s depth and width. Casio remains the source for the official case block.
- Casio rates accuracy at plus or minus 30 seconds a month and battery life at about 7 years on a CR2016 cell.
- The module is Casio 3224, per the official F-108WH page and the Operation Guide PDF for that module.
- Illuminator is the built-in LED backlight. A LIGHT button press lights the display for dark rooms and early mornings.
- The Amazon SKU on this listing is F-108WH-1ACF, ASIN B0053HBJBE.
Size And Everyday Fit
Casio’s 44.4 × 42.6 × 10.3 mm case is larger than the classic F-91W. The face reads bigger on the wrist, and the 31 g resin build still stays light for all-day wear. In my opinion it suits people who find the F-91W too small and want a clearer digital window without jumping up to a chunky AE-series case like the Casio AE-1500WH.
The resin strap is the usual Casio multi-hole band. It is easy to trim for a first fit, and it tolerates sweat better than leather dress straps in this price band.
Water Resistance Stays At Splash Level
Casio markets the F-108WH as water resistant and stops there. No 5 BAR, no 10 BAR, and no 100 meter claim appears on the official F-108WH product page. Casio’s water resistance FAQ is clear that a plain Water Resistant mark without a BAR figure covers rain and hand washing, and it does not cover swimming. Keep this watch out of the pool, the ocean and the shower.
Amazon’s B0053HBJBE page is the messy part. One section has claimed 100 meters of water resistance, while another has claimed 30 meters. With that conflict, Casio’s own rating is the safer guide. If a bullet still shows 100M when you open the page, treat that as Amazon copy. It is separate from Casio’s official rating.
Illuminator Light And Daytime Read
Illuminator is why many people pick the F-108WH over older Casio digitals with a weaker glow. Press LIGHT and the LED fills the display for a quick night read. In daylight the large digits stay easy to parse for time, day and date once you learn the MODE cycle.
The layout will feel familiar if you already own an F-91W or an A158WA. MODE steps through time, alarm and stopwatch style functions, and the side buttons match the usual Casio muscle memory. Exact mode charts live in Casio’s Operation Guide for module 3224.
Battery Life And Accuracy
Casio rates the CR2016 cell at about 7 years and accuracy at plus or minus 30 seconds a month. That is the official line for the F-108WH, and it matches the module guide for 3224. A multi-year battery is a quiet upside for a daily beater. You set it once, and you skip the charger cable loop that comes with many smartwatches.
F-108WH Versus The F-91W
The F-91W remains the thinner, smaller classic. The F-108WH is the everyday alternative when you want a larger case, Illuminator branding on the case, and a backlight Casio positions for easier night reading.
- Pick the F-108WH when case size and Illuminator matter more than the slim F-91W profile.
- Pick the F-91W when you want the smallest classic Casio resin digital already covered on this site.
- Both stay splash level for water. Neither is a swim watch on Casio’s unmarked Water Resistant guidance.
- If you need a much larger digital with a long battery line, the AE-1500WH review is the next step up in case volume.
- If you want a stainless bracelet digital with a different dress vibe, the A158WA review is the soft link for that look.
Casio also sells other resin digitals in this price band, including the W800HG, but this page stays on the F-108WH-1ACF.
Who Should Buy It
- Buy it if you want a budget Casio digital with Illuminator light and a larger face than the F-91W.
- Buy it if a CR2016 cell rated around 7 years fits how you like to ignore battery chores.
- Buy it as a simple work and errand watch when steel, sapphire or smartwatch apps are off your list.
- Look elsewhere if you need confirmed swimming use, a dive rating, or a thin F-91W style case.
FAQ
Is The F-108WH A 100 Meter Watch?
No. Casio’s official F-108WH page lists water resistant with no meter or BAR figure. Casio’s FAQ treats that mark as rain and hand washing only. Amazon has shown conflicting 100M and 30M claims on the same ASIN. Go by Casio’s rating.
Can I Swim With The F-108WH?
No. Stick to rain and hand washing. Keep it out of the pool and the ocean.
How Big Is The Case?
Casio lists 44.4 mm height, 42.6 mm width and 10.3 mm depth, at 31 g. Amazon’s measurements table lists about 42.4 mm diameter and 10.26 mm thickness.
What Battery Does It Use?
Casio specifies a CR2016 cell with an approximate 7 year life, and accuracy of plus or minus 30 seconds a month.
How Does It Compare To The F-91W?
The F-108WH is larger and carries Illuminator lighting for night reads. The F-91W is the smaller classic. See the F-91W review if you want the thinner profile.
Is This The Same Watch As The AE-1500WH?
No. The AE-1500WH is a much larger digital with its own review. See the AE-1500WH review when you want that bigger case.
Bottom Line
The Casio F-108WH-1ACF Illuminator is a light resin digital for everyday wear, with Casio’s water resistant mark at splash level, a CR2016 cell Casio rates around 7 years, and Illuminator light for dark rooms. At $20.97 from Amazon.com as checked Nov 2, 2026 at about 9.55pm Manila, it is the F-91W alternative when you want a larger face and a stronger night light without leaving the Casio resin lane. Keep swimming off the table, ignore Amazon’s conflicting water meter claims, and confirm the seller before you buy.
