Please let me know ASAP if for any reason the connectors you were able to purchase do not match or are substantially different from the Moko ones we purchased and modeled into the CAD. It is imperative this set of bands function as close to actual Apple Watch bands as possible, so please test-fit them into an Apple Watch head to verify this functionality. If for some reason you do not have access to an Apple Watch, let me know as soon as possible and I can send one to you.
