There are a couple of more ways too
The number on the clasp of the bracelet should end in either 0, 14, or 18 identifying steel or 14k or 18k.
Also, the date of production and color of the gold can both be used to make an educated guess.
Rolex 14k or 18k
My question is, how do you find out if a rolex is 14k or 18k. I have a rolex 2tone gold/stainless ref#16013 blue dail

Wrong number
But K5 should be about 1987 which is VERY late for a 16013. I would think it would be 18k. The long number below the K5 should be the model number of the bracelet and the last two digits should tell you.
