Secondary / used

full set · insufficient_data

Did not fabricate a number. Same cheap/ubiquitous pattern as the other Casios in this catalog -- likely tracks new price closely, not independently verified here.

Sources: eBay/Jomashop search surfaced only generic listings or a different sibling model (GAB2100-1A, not this exact GA-2100-1A1) -- not used as a comp per this project's reference-matching discipline

Source note

Cross-verified via casio.com (official), G-Central (G-Shock fan/spec site), WatchCrunch review. Catalog MSRP ($110) matches the $99-140 range found. Octagonal case -- diameter_mm/lug_to_lug_mm use the conventional retailer measurement convention for this shape, not a true round diameter.
