Casio's Fabric-Strap F-91W Sold Out Within Days in the US, Then Restocked — Here's the Classic F-91 Module It's Built On

Casio's fabric-strap variant of its iconic F-91W, the F-91WF, sold out within days of its US launch despite costing roughly double a standard F-91W ($45.95 vs ~$22). On September 15, 2026, all three colorways (black, navy, olive) returned to sale. The module is identical to the classic F-91W: a 38.2 x 35.2 x 8.5mm case with a 1/100-sec stopwatch, daily alarm, auto-calendar, and green LED backlight — only the woven recycled-PET strap differs.

This F-91WM-7AJH shares that exact same module and case dimensions, in stock now through CDJapan.
