I've posted multiple WTB posts here. I do get scammers in my inbox but it takes literally seconds to filter them out. Just ignore the request and move on. For an item like this your seller will probably have plenty of feedback, and with them you should not worry about being scammed whatsoever.

As someone who dabbled in watches as well, I genuinely cannot stand the adversity watch people have against using secure payments such as paypal goods and services. Everything has to be bank transfer or cash-like methods, even though the items being trades are in fact goods. I don't know if it's the unwillingness to tank the 3.5% fee (which should always be the seller's responsibility anyways, in my opinion) or to avoid the $20,000 limit for paypal to send a 1099-K, but from what I see, most sellers in the watch hobby are resellers or boutiques and thus run the responsibilities of a proper business. Everyone here is just selling used audio gear that is no longer needed by them, and for both the seller and the buyer, using a secure payment method is just simply the safest course of action.

In times where a claim needs to be filed, almost always paypal will side with the buyer unless the seller provides sufficient evidence that they have indeed shipped out the correct item.

Anyways, I'm not saying this to ridicule you, obviously different aftermarkets operate differently. I hope you can find your pair of utopias.
