F91W Lap

F91W Lap is a Casio F-91W movement rehoused in a machined stainless steel case with a high polished front, built in magnets and one big lever to start and stop the stopwatch. It has the same insides as the wristwatch, but turned into a handheld, pocket or wall timepiece that attaches to any ferrous surface.

We have been celebrating the F-91W for a while. Designed in 1989 and unchanged since, it keeps time to about ±30 seconds a month and runs for 10+ years on a single coin cell.

Press the lever to start and stop. The two side buttons do everything else an F-91W does: switch modes, set the time, hit the light. Stopwatch resolution is 1/100 of a second.

All parts are machined stainless steel. The face is mirror polished, everything else is bead blasted. The display sits under a 29.5mm glass crystal, press fit with a PTFE gasket and mounted flush with the face. Four screws hold it together, so a battery change is a screwdriver away. Two magnets embedded in the back stick it to the fridge, a whiteboard, a steel shelf, the side of a machine. Wherever you want a timepiece to stay put.

Ships with a multicolor paracord lanyard to attach or clip to stuff.
