Welcome Ethan. Press the flower button on your camera to put it in macro mode. This will allow it to focus for close-up shots.
Nearly verything you need to know is written on that dial. It's a Seamaster De Ville model - or at least it appears to be. These were made in the mid 60's. The date window tells me it has a movement from the 56x series, a 562 most likely. A watchmaker could open it up (it comes out the front) and get the reference number from the inside of the caseback and the serial number off the movement which will tell the year of manufacture.
