How much do you think these watches are worth?

I saw a man on Twitter who says he owns over 50 watches made 1893-2005. He invited me to a website he has that shows some of them. I wrote down data on some of them. What are their values do you think?

New Jaeger-LeCoultre "Memovox ahve date cost $14,500 steel


New basic Patek Philippe watches cost $17,400-$23,600, old one of 1893 and 1926 probably sell much higher at auction
