The way to buy in the pre-owned market.
I wanted a Ball watch, but new is too expensive so I decided to try the pre-owned market, which led me to Chrono24. I very much liked the various safeguards which give protection when you buy. Chrono24 listed a number of Ball watches, but my eye was attracted to an unused 2025 watch, the Engineer King, with day/date as I wanted. I offered the asking price and am delighted with the watch, which is on my wrist as I write. The buying process went smoothly. I recommend Chrono24 if you're thinking of buying in the pre-owned market.
