Use these metal, 10 sided "keys" to remove the casebacks used on some classic timepieces. Older models by Benrus® and others had the ten-sided back design which required these special openers. Set includes eight sizes measured across, flat to flat side: 18.2, 20.9, 22.9, 24.9, 27.2, 28.1, 29.2 and 32.0mm.
