Tough choice between a pre-owned submariner and a new submariner

[Hank6431]

Hi guys,

I want to purchase a rolex submariner, and I never owned a rolex watch before. First, my wrist length is about 6.25 inches. Will the submariner fit my wrist well? I asked several local dealers, and basically have two options now. One is a pre-owned submariner (16610) with F serial. The condition is quite good, and it has complete box and papers. The price is 6000 (US dollars). The second option is to buy a new submariner with date (116610), and the price I can get is around 7700 (US dollars). Can you guys give me some good advice regarding to these two options? Thanks!
