#quartz is nice and I'm glad for crystal derived time, but I voted #cinnabar. Quartz is omnipresent, but the trip with single digit aged me and my dad and the guide to Obermoschel was unique. I'm working with quartz for clock signals, have some nice oscillators (Rb Controlled, heated) but my picture shows an old russian low frequency quartz bar I'm didn't come around to use yet. #mincup23 #teamquartz
