The LAB02 required a much longer axis for the gear train, and, without having a top bridge, needed ball bearings instead of rubies on the mainplate to add strength and stability. • #corumwatches #watch #reloj #montre #orologio #time #timepiece #watchcollecting #watchcollector #watchfam #watchnerd #watchgeek」6月15日 23時02分
