He is based in Ecuador/Peru.
Don't let his imperfect English fool you.
He claims to have many watches and watch parts inherited from his father's passing.
He either tries to get you to send funds via PP G&S and then claims the account is frozen so can't withdraw or refund.
Or he asks for money via PP F&F to cover just the shipping but then never sends the goods nor provides a refund.
(I also added him to the known scammers list thread).
