Niks

Hi I was traveling on shinkansen Nozomi on 31/03/2018 from Hiroshima to Osaka and I have lost my Alta Fitbit black watch on the way. I have tried to find it, but have not been able to trace it. Is there an option that I get notified if it gets deposited in the lost and found department by someone at any time. Or can you please give any other options to find it or report loss of it. Thanks
