Apple watch series 5 - 44mm white ceramic sunshine Sp Lp

When I participated in a product campaign, I got the Apple Watch 5 Series White Ceramic Case Suns as a model for the Sport Loop. But I have no interest in using it because I already have the 3 Series watch in my hand. So I want to sell this watch which I got as a prize. So please humbly inform me that it should help me with that. The product is fully packed and there is no damage.
