Pierre DeRoche uses an exclusive for the Pierre DeRoche movement in the SplitRock watch, which is the Swiss made Dubois Depraz PDP 4001-1 automatic. It uses a micro-rotor so that you can appreciate more of the decorated movement. There are lots of large blued steel screws and cotes de Geneve polish, as well as some perlage on the movement. “Vallee de Joux” – the origin of the manufacture, is engraved on the movement. The appearance of the movement is rather phenomenal, making the watch a pleasure to look at both front and back.
The innovative chronograph function features three concentric dials inside of one another. The dial has three rings and three hands. The larger, thin, red hand is for the seconds, and the smaller minute hand is for the chronograph minutes. Under that is an even smaller hand for the chronograph hours (you can’t see that hand until the minute hand moves). This clever system allows Pierre DeRoche to insert a fully functional 12 hour chronograph into one dial. There is also a subsidiary seconds dial for the time above, overlaying the time dial. Additionally, the date window was elegantly placed as a part of the watch dial, with a little bulge.
Overall, the SplitRock dial is quite unique in design and is three dimensional, but also takes into consideration rules of symmetry and traditional design, ensuring that it looks attractive.
There are a lot of art deco elements to the design, as well as an architectural slant. As you can see, the watch makes a bold statement on the wrist, even more so than looking at it alone. Anyone from a seasoned banker to a classic car connoisseur can sport a watch like this with ease. The design is contemporary yet mature, making it suitable for confidant collectors who appreciate an elegant look.
