These are the clock adjustment knob and the trip meter reset knob for the Honda CX500 and CX650 Turbos. Also used on the Euro 500 and 650 models as well as the CB1100F and VT250F in '82-'83. The clock one is the longer one (37461-MC7-611) and the trip meter reset is the shorter one (the trip meter knob is indeed the shorter one! (37204-MC7-611). The originals have some hollow spaces in the back. That works for injection moulding but makes them too fragile in 3D printed versions. So I left them solid.

UPDATE: The rim between the bottom counterbore and the knurling on the outside was too to print successfully. V2 reduces that recess by a millimetre to allow more reliable printing. Final update: circular spindle hole portion was not exported to STL model (glitch).... fixed.
