I have a Bernoulli watch here for sale. it works just fine. It does not need batteries it works off of motion. It is in very good shape with no scratches on either side of the watch. If you have any questions or would like to come view the item, you can contact me via Craigslist, or you can call or text 509-2one7-5149 and ask for Anthony. The best and fastest way to get ahold of me is by Text message or calling!!!!! Also if this item is still listed that means that it is still for sale.
