How the Casio F‑91W actually wears

Tim's original photos show scale, fit and strap details that polished product images cannot.

Close view of a gunmetal Casio F-91W on a black leather strap worn outdoors — On the wristA sharp real-wrist view of the gunmetal F-91W on leather, showing how compact the case remains even after a dressier strap swap.

Underside of a black leather strap fitted to a Casio F-91W with Bubble the dog in view — Strap and fitThe reverse angle shows how neatly the leather strap wraps the wrist without repeating the dial shot.

High-intent comparison
