These measure almost 1" X 3/4" (not including the wrap around), at their widest, and are not marked. Sorry, I can't figure out if this is ZODIAC, MIDAS, or AQUARIUS, up to the buyer to decide. Please look at all photographs, as they are part of the description and ask any and all questions prior to looking. Thanks!
