Most Rolex owner we talked to never considered doing that either. However Rolex movements are really nice and it feels good to see your movement or being able to show it to others... This is the idea behind our product.
They have actually been made in collaboration with someone who worked at Rolex back in the days. They are made in Geneva and the quality is really good.
No risk of leaking, our product has been tested for that. I am attaching a picture. Will post more when I get a chance to.
