Once the Czech military specifications were in, Longines switched to the CHEAPER Cal. 15.68, and this is the movement found in most military-issue Longines “Tartarugone” watches. \n\t \n\tPodla tohto clanku \n\thttps://grailium.com/product/watch/longines-observatory-competition-chronometer-cal-14-68z-15-68z/ \n\tvsak bol 16.58Z jednym z najlepsich kalibrov tych cias\n \n"
