The Roamer Swiss Matic Swinging Heart 550661-41-52-05 is a magnificent, stylish, Swiss Made mechanical (automatic) watch. Under the hood you'll find the reliable 28800bph STP 5-15 movement, which is similar to the ETA2824. Of course the dial is protected by sapphire glass with an AR coating and there is a caseback window. 

The dial of the watch is what makes the watch special: an  open heart window, through which you can see the movement ticking away on your wrist.
