The new Pierre DeRoche watch is built from two extremely hard materials - sapphire and titanium. It stands out due to its visible sapphire bridges. The transparent movement allows watch connoisseurs to admire the originality of its one-of-a-kind complication.
The automatic movement, the heart of the model, represents an exclusive Dubois Depraz caliber. It is constructed with 58 jewels and incorporates a 22K pink gold decorated and engraved oscillating weight. Its central bridge has 12 pivots, 6 sapphire seconds bridges featuring 6 retrograde seconds hands on gears. Besides hours, minutes and retrograde seconds, the mechanism animates the date function.
