Watchuseek team met with Pierre and came away with the appreciation for his passion for watchmaking. Pierre is not about mass marketing and mass production, but is about appreciating watch an art form.

Highlights of this year's collection included Bonnie & Clyde watches, GMT function with half-hour time setting, and simple yet elegant ladies Pure Nacre watch. It was impressive to see the focus on ladies watches.

Bonnie & Clyde
With its perfectly choreographed dance of six retrograde hands, the TNT Royal is an endless source of fascination. Not content with staging a complication that is unique in the world, it now explores the field of futuristic materials by introducing a bezel in itr²®. This totally hypoallergenic composite material is six times lighter than steel and four times lighter than titanium. Created from carbon nanotubes, itr²® is transparent. Once charged with ceramic or carbon particles, it turns white or black as desired. Over and above its excellent technical performances, itr²® provides a unique visual effect, echoed by the six seconds bridges and the central bridge alternately draped in sparkling white by means of a stabilized silver coating, or in black.

Pure Nacre
Pierre DeRoche has composed an anthem to pure, uncluttered lines with its new GrandCliff Pure Nacre. Destined to establish itself as an ageless feminine classic, the timepiece embodies a vision of watchmaking pared down to essentials, retaining only complications that are useful in daily life. The understated date and power-reserve indicator are beautifully highlighted against the backdrop of a natural blue-tinted natural mother-of-pearl dial – framed by a round and slender case graced by clean, sleek lines. At its heart beats an automatic movement, offering a fine example of what can happen when mechanical horology meets exquisite femininity to mark off a time that will transcend the passing years.

GMT 1/2 Hour
Pierre DeRoche enriches its TNT Royal Retro with a GMT display adjustable to the nearest half hour not via a corrector, but instead using the crown. An extremely rare phenomenon! To avoid any loss of precision during adjustments, the GMT hours and minutes hands advance in 30-minute increments to guarantee exact half hours, without the movement stopping. A third indicator appears on the white part of the subdial if it is daytime in the zone of the second time zone; or in the black section if it is night-time. Meanwhile, the TNT Royal Retro signature retrograde seconds hands pursue their fascinating path. To spice up the overall effect, two of the six original hands vanish in the lower section of the dial to provide space for the GMT indicator.
