Refurbished Apple Watch Series 1 and Series 2 now available from Apple
Right now, refurbished Apple Watch units only come with Sport bands, but you can choose from either 38mm, or 42mm models, with stainless steel, or aluminum cases. To see all the available options, check out Apple's website at the source link below.
While not technically new, refurbished products are "like new". In the case of Apple's refurbished Watch models, these are tested and certified by the company, and come with 1-year warranties plus free shipping and free returns (within the US).
