Porsche Design P'6520 Compass Watch
It's about time someone did something with all that room inside the watch case. The Porsche Design P'6520 Compass Watch ($TBA) uses it to split the watch in half, with the upper portion devoted to a simple three-hand watch featuring a Swiss automatic Sellita caliber movement, titanium black PVD case, and AR-coated sapphire crystal. The bottom half holds a removable liquid compass that works in both the Northern and Southern hemispheres, and is viewable thanks to two mirrors on the compass face and bottom of the watch section that click into place when opened. Water resistant to 50 meters.
