Vintage datejust 6605 VS 1601 Help

[jperalta86]

Looking for feedback on a vintage datejust listed for sale, I placed a deposit on the watch because i love the look but im concerned if the dial is accurate to the production year.

http://www.vintagegoldwatches.com/pr...just-18k-1958/

The listing dates the watch 1958 but mentions that the model number is a 1601, is that possible? I thought datejust ref 1601 started in 1960. Should this be a ref 6605 based on year?

My other concern is the dial print, under the Rolex crown, is it just me or does the Text seem a bit low under the logo crown?

The seller has 400 plus good reviews on ebay with a 100 percent good rating and their website looks great in my opinion.

I love the watch but im concerned any help would be much appreciated.
