The Porsche Design Diver Watch in Titanium. Model reference P6780. The Porsche Design P’6780 Diver watch is a fantastic timepiece for those able to appreciate what it does and where it came from. Porsche Design released the P’6780 Diver watch in 2010, though watch lovers recognized the case and much of the design from a watch that Eterna released in 2008 called the KonTiki Diver. Eterna designed the highly ambitious KonTiki Diver as testament to what the brand was all about. With a unique yet useful design, the 1000 meter water resistant KonTiki Diver was used to help return Eterna to the US market. A watch lover’s dream, the only problem with the Eterna KonTiki Diver was that it was a marketing bomb. Porsche Design clearly saw the appeal of the design and decided to transform the Eterna KonTiki Diver into the Porsche Design P’6780 Diver watch. Today, the Porsche Design P’6780 Diver watch remains quite rare. The case is just under 47mm wide and quite long given the design of the case. It is also 17mm thick. The case has an inner section that pops up securely as you press two buttons on the side of the case. Popping the watch up not only is a neat trick, but is also what unlocks the rotating diver’s bezel. Not only does turning the outer bezel move the inner bezel (all on a watch with 1000 meters of water resistance), but the sound it makes is fantastic. The case uses some special screws and has articulating lugs, which help the sheer mass of the case fit securely on a range of wrist sizes. It is quite rare for a watch design to be so focused on being large, but also wearable. With a properly-sized strap, the Porsche Design P’6780 Diver wears extremely comfortably. Changes to the case from the Eterna to the Porsche Design are evident, but minor. Most of the changes to the watch from the prior Eterna version are on the dial – though it is not just a matter of a re-badged watch – the Porsche Design piece is very much a Porsche Design watch that simply borrows from an incredible design that didn’t work for Eterna. The Porsche Design P’6780 Diver dial is deep with the rehaut-style internal rotating bezel that steeply slopes down to the main dial. Here, you see something much more simple compared to the KonTiki Diver. The dial features applied polished and lume-filled hour markers, along with legible diver’s style hands. Just to be unique, the date window is placed at 9 o’clock along another inset horizontal line which is part of the dial design. The side skeletonization of the case is neat to look at and when the inner case is popped it locks into position. Attached to the Porsche Design P’6780 Diver watch is a high-end caoutchouc rubber strap, which has been specially designed to match the case. The strap is very thick and feels secure. It is attached to a butterfly-style deployant clasp that actually has a separate section which can optionally open up as a diver’s extension. Inside the Porsche Design P’6780 Diver watch is a Swiss ETA 2892-2 automatic movement. A simple movement, it is an accurate workhorse. The watch comes in original packaging, with a set of documents.
