These measure approx. 3/4" X 1/2", and are marked CHRONO, GOLD FILLED on the back, please see photos! SORRY, all I can read on the front is NAVAL, the rest is really worn! These may need a good cleaning / polishing! Please look at all photographs, as they are part of the description and ask any and all questions prior to looking. Thanks!
