I don't have a backyard so I take a train into Manhattan and walk from 8th street to Wall street.
Plenty of sights to see. If I go down Lafayette St, there is an artist's gallery with some great pictures and less people than Broadway.

The magazine of watch porn is called the Robb report Watch collector.
There you can find sexy watches with black diamonds, platinum and swiveling top parts.
Some of the more saucy ones are transparent so you can see their inner workings.
If you don't want to wind in public there are self winders for your shy watch.

There is this magazine store on 14th before you get to 5th, been going there for at least 5 years.
They have an art section filled with all sorts of expensive art books.

ImagineFX, a magazine on digital artwork is probably more than $8, its an import from England.
You do not want to know how much the subscription is but I think its worth it for me.
Its mostly for digital painting but every once in a while they sneak in a 3d piece and talk about postwork.
