Patek Philippe

Does anyone have a few great reference images I can look at to see what the case should like like on a 3940j final series? Ideally with good close ups, etc. I've found a few I *think* are good but want to be 100% sure before pulling the trigger!

Hoping for some good side profile shots too

So the bottom side should have similar ridges to the top?
