Rolex & Tudor make the best watch case in my opinion. The Rolex Oyster case is highly water resistant, does not utilize screws to open and is one piece. The Rolex & Tudor case has the case-back on one side that is opened and closed with something that looks like a ball from a play pen at a fast food restaurant. The opposing side contains sapphire crystal. This no-nonsense wristwatch case design is the best in my opinion! What are your thoughts? #Rolex #Tudor #TimepiecesForTomorrow
