Unless it’s a Stainless Daytona. Those are bullet proof if purchased at retail(good luck).
But yes paying full pop for 98% of the watches out there is a bad idea and you’ll take a huge hit.
I flipped watches for about 5-6 years. Was great fun and paid for a pile of cues.
I haven’t bought a watch in 4 years. And that was the first watch I bought in 7-8 years at that time. Was a new model of an old watch I wear daily. A Sea Dweller. I paid €11,400 for it (retail) I haven’t looked as I’m not selling but it’s trading over retail.
I never wear the fancy stuff anymore
