Reminds me of the Seiko UC-2200 I picked-up at a computer show in '85 or so.

Wristwatch with a 40x24 display screen.(pixels, not characters)
magneto-coupled non-contact interface to a keyboard base with plug-in
application ROM pack, BASIC language programmable, integrated
dot-matrix printer.

Anybody got a BR2325 button cell battery?

I'm not sure how you're measuring keyspace, but this looks close.

horizontal edge-to-edge looks like 18.0 mm
vertical at 10.0 mm
can't estimate vertical stroke, but motion is involved.

Label calls it a
SEIKO UC-2200
CONTROLLER MODEL NO. UM01-0020
Hattori seiko co. ltd
No 457624 made in Japan.

FCC ID C4Z7NSUM0120
