Vipoutlet has many series 7 stainless steel cell versions available for the Apple Watch. All grade A or better. I just bought a series 8 with Milanese loop for $400 and was brand new. Only the shrink wrap was torn. If there are any issues they offer free returns but never had a problem. Typically grade A is always brand new condition. This appeared to be the best deal.
