Information and value of a 1946 Rolex 3131

[Tlon]

Hello,

I inherited this Rolex from my grandfather. I'm trying to learn as much about it as I can, and to get a sense of its value, if possible. I gather it's a 14k 3131 and if I'm reading the serial number correctly (517xxx) it was produced in 1946. Anyway to tell if its all original? It seems to work extremely well -- the slightest movement starts the movement when it's been wound down.

You'll see from one of the photos that I inherited it with a very 1980s 14k gold nugget bracelet (59 grams).

I am planning on trading this for a newer Rolex submariner, so I'm curious about its value. I know trading it may seem odd (or even sacrilegious), but knowing my grandfather he'd much prefer I had a watch I wore regularly rather than keeping this in a safe. Even so, I'm fascinated by the watch and would like to know more about it. Are there any good references online on the 3131, history, movement, etc.

Many thanks!

you have a nice 3131. These watches came from regular yellow (what you have) to deep pink (almost purple) color. Excellent three piece BB. As far as value - look it up.

As far as trading this watch for a Sub - be prepared to add a lot of cash.
