Knockaround Sunglasses Review Limited Edition GI Joe Glasses I was very lucky to find an approved service centre that could source a brand new original replacement dial. Victorinox mach 6 power guage limited edition new dial & sapphire glass mint the original strap and clasp has slight signs of use but is in very nice condition.
