Up for sale is a VULCAIN CRICKET alarm watch. I don't know anything about this type of watch and I don't know how to take the back off to picture it. The tag that my Dad had attached says the alarm does work. The watch is wound tight but I did set it and when I rock it back and forth the seconds hand starts right up but only goes for a few seconds. I rocked it several more times and each time the hand moves for a few seconds. I hope that helps.  I don't know when it was last cleaned and serviced and as with all vintage watches that should be done when it's received. Please check all my pictures and bid for what you know about vintage watches as I am selling it AS IS. If you have any questions please let me know and I'll try to help.  **** BUYER TO PAY $8.50 SHIPPING IN THE U.S.   ****
