Not really much point in this in my opinion. Sorry but you may as well take get the watchmaker to open it for you and take the pictures before or after it is serviced.
The watch is genuine not sure that the crown (winding knob on the side) is original. It is very much worth getting it serviced (oil, lube and adjust) by a watchmaker with experience in vintage watches. They may also be able to find the correct crown, and it would look much better with a new crystal (glass on the front) not many people here would recommend sending it back to Omega, as they are likely to replace pretty much everything and charge you a small fortune for doing so. Don't try winding it up again until after it has been serviced as you may well cause damage to the movement.
Once the above has been done, there is no reason why you cannot wear it every day for many years to come. Unless swimming, mountain biking etc.
And if you let us know where in the world you are, someone may well be able to suggest a competent watchmaker for the service.
