Just as clarification, dropship and made-to-order are not synonymous.

Dropship generally means the item you buy already exists and is in someone else's warehouse. You buy it from me, I send the order to a third party who owns the stock, they ship it. I square up with the third party.

Made to order is similar, except the item does not actually currently exist. You buy it from me, I have someone else make it on my behalf, you eventually receive it in the mail.

This particular deal sounds to me like they are taking pre-orders. They will wait until some threshold is reached, then start the production process, then ship directly to you. I don't know where in CN watches are actually made, but I can guarantee you that there is a specific city where all the manufacturers and parts suppliers are.

Further, these will ship directly from China to your door to avoid tariffs. Any purchase under $800 is currently tariff free under Section 321. I doubt many $100k watches get sold, and those would go through a different channel anyway.

Shameless plug: I just quit my job in consumer goods supply chain. If anyone you know needs help on this stuff, reach out!
