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.
