You CAN(just barely) use a fingertip. I have the other two items, possibly a whole band with stylus to sell(Pulsar LCD calc, not Citizen). They did not originally come with a stylus(in the clasp or otherwise) - it wasassummed you would use a ballpoint pen or such.
Darn, not finding my scan of the Citizen instructions, so I will have to rescan. Write me when you receive your watch.....you'll never figure out the setting sequence without the instructions. I've sold 2 of those, and each time the buyer said,"it won't set". They send it back and I have no problem....I go over fine points of the instructions and they get it.
