Pierre DeRoche uses an exclusive for
Pierre DeRoche movement in
the SplitRock watch, which is the Swiss made Dubois Depraz PDP

rather phenomenal, making the watch a pleasure to look at both

chronograph function features three concentric dials inside of
another. The dial has three ring and three hands. The larger,
thin red hand is for the seconds, and then there is a smaller minute
hand for the chronograph minutes, and 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
dial. There is also a subsidiary seconds dial for the time
overlaying the time dial. I also like how the date window was
elegantly placed in as part of the watch dial, with a little
bulge. Overall, the SplitRock dial is quite unique in design and
quite three dimensional, but takes into consideration rules of
symmetry and traditional design ensuring it looks attractive.
There are a lot of
art deco elements to the design that is also very architectural.
The design is contempory yet mature.
