Another pulsometer following on from yesterday. Museum piece number 10. Lovely blue hands on porcelain dial.
Fresh arrival! The grandfather of all 320/321/CH27s out there! Early execution, and movement serial number 132(!). Any lower observed? Non-shock protection, and most likely from the first production year 1943.
