Materials:

       Common sense is the best judge of quality materials. A top-notch replica will weigh the same as the original, and of course someone selling a "solid gold" watch for $200 is fudging the truth. However, triple-wrapped 18-karat gold is frequently used and a sign of good quality. It's up to you to choose how close to the real thing you want your replica to be, and that decision will affect the price you pay.
