Quick answer: Measure your wrist with a tape. Under 15 cm suits compact models such as the LA680 Vintage or an LTP dress analog. Between 15 and 17 cm suits almost everything, including the slim GA-2100 G-Shock. Above 17 cm comfortably carries large cases such as the GA-700 and G-STEEL.
Fit is the most common reason an online watch order disappoints, and the easiest problem to avoid.
Start by measuring your wrist
Wrap a tailor's tape around your wrist just past the wrist bone, towards your hand. Snug, not tight.
No tape? Use a strip of paper or a shoelace, mark where it overlaps, then measure that length against a ruler.
Write the number down. Everything below depends on it.

Treat these as starting points. Two people with the same measurement can suit different watches depending on how flat the top of the wrist is.
Three things that matter more than diameter
Case thickness decides whether the watch slides under a shirt cuff. Slim retro models and dress analogs clear a cuff easily. Thick analog-digital G-Shocks do not, which becomes a daily irritation if you wear long sleeves to work.
Lug-to-lug is the distance from the top lug tips to the bottom lug tips. If it exceeds the flat part of your wrist, the watch overhangs and looks oversized whatever the diameter says. Resin G-Shock cases curve downward, which helps.
Weight is often the real decider in Accra heat. A resin G-Shock is light. A steel bracelet or a G-STEEL is not. Across a humid day that gap is obvious.

Buying online without trying it on
Four checks that remove most of the risk:
-
Measure a watch you already own and like, across the case, then compare that number with the listing.
-
Look at wrist photos, not the product-only shot. Catalogue images make everything look the same size.
-
Prefer a steel bracelet if you are between sizes, because links can be removed. A resin strap is limited to its existing holes.
-
Try before you buy if you can. Fifteen minutes at the Achimota Mall store settles what an hour of comparing photos will not.
Buying for someone else
Borrow a watch they already wear and measure the case width.
If you cannot, choose compact. A small watch on a large wrist reads as a style choice. A large watch on a small wrist reads as a mistake.
The LA680 and the LTP analogs are the safest sizes in the catalogue. A gift voucher removes the question entirely.
Frequently asked questions
How do I know what size watch to buy?
Measure your wrist circumference, then match it to a case size. Under 15 cm suits compact models, 15 to 17 cm suits most watches, and above 17 cm carries large cases comfortably.
Which Casio is best for a small wrist?
The LA680 Vintage models from GH₵850 and the LTP dress analogs from GH₵450. Among G-Shocks, the slim 2100 case is the most wearable.
Is a G-Shock too big for a small wrist?
Some are. The GA-700 is large and thick. The GA-2100 is noticeably slimmer and is the usual recommendation.
Does case thickness matter?
More than most people expect. It decides whether the watch fits under a cuff and how it feels through a long, hot day.
Can I resize a Casio bracelet?
Steel bracelets are sized by removing links. Resin straps are limited to their existing holes, so check the range before ordering.
