Take it to an independent authenticator or watchmaker who will open the case and inspect the movement, then compare serial and reference numbers and check each part for originality. Ask for a written report with photos.
Obvious fakes show poor printing, a cheap bracelet or a price that's too good. The best counterfeits only reveal themselves inside, so for any watch of real value, pay for a professional authentication before you buy.
An insurance appraisal estimates what it would cost to replace the watch at retail today, which is often higher. Fair market value is what a buyer would actually pay and is the figure used for sales and estates.
