Well first i want to say how nice of a watch i got for $108 bucks!!! very nice,fast shipping, and great communication with Josh. Fist time buying a rep and I highly recommend him. Ok to my questions. How long will my watch run on average, once i leave it on my nightstand? also my beginmariner sounds like it has a small BB or something in it when i shake it a bit. Is this the automatic movement? I am new and these may sound like stupid questions but i am here to learn and take in all the info i can.
