Sqad, or anyone else who worked in the medical field, remember using one of these to time coagulation and other tests. A vintage mechanical stop watch dating, I'd estimate from the '60s. Obviously all timers would be digital today...Somehow it jumped into my pocket shortly before I left working in the lab:) The opening question is, of course, from "Carry On Doctor".
The ear-lobe seemed to be the choice location for this test. Anyway, I recently replaced the stem on this watch, and cleaned and oiled the movement...Ticking away like it did eons ago!
