If you're comparing apples to Apple's (pun intended), the biggest difference is going to be the length of the cord. Apple gives you 3 feet and Insignia gives you 6 feet. If you are in the market to buy a replacement and are comparing Apple to Insignia, then price will also come into play. Quality is comparable, but Insignia is less expensive, with a longer cord. The end result is the same with both products ... a charged watch.
