Pierre DeRoche TNT Royal Retro RB Automatic Swiss

Pierre DeRoche keeps churning out new models powered by their exclusive caliber from the complications specialist Dubois Depraz. As its numerous siblings, the new automatic Pierre DeRoche TNT Royal Retro RB offers you a rare retrograde display complication with whole six seconds hands strategically positioned around the dial.

It’s not what you know, it’s who you know. Yes, I knew that even mentioning the proverb in public is a clear indicator of a, well, not very successful person in the house, but it still never fails to come to mind when you think about brands such as Pierre Deroche.

Established in 2004, it is owned by Mr. Pierre Dubois who happens to be a brother of Mr. Pascal Dubois who happens to own the famous Dubois-Depraz company that happens to specialize in creating all sorts of complication modules for the Who Is Who of the Swiss watchmaking industry.

Known all over the world for their sophisticated, yet highly efficient and reliable complication modules and complete movements, the company has become a source of exclusive mechanical calibers for the young Swiss brand. Add into the mix creative minds of the persons standing behind our Perre Deroche brand, and you get a constant flow of watches that not only look expensive but are also different.

While the functionality is modest (it only displays hours, minutes, seconds and date,) the way the data is presented is nothing, but impressive. Featuring a unique complication designed by Dubois Depraz, the watch sports whole SIX (yes, six! each responsible for its own ten seconds of any minute) retrograde seconds hands that, like some strange sea flower, are always in a state of constant motion feeling the flow of time with their tiny steel tentacles.

Although the mechanism itself is not particularly large (it’s my understanding that the base movement is a mundane ETA three-hander with a nice add-on module) and doesn’t require an oversized case to fit in, the watch is nevertheless presented in a huge stainless steel body that underlines the deliberate sporty attitude of the Pierre DeRoche TNT Royal Retro RB Automatic.

More than 47 millimeters in diameter, the multipart case is done in stainless steel with some of its components treated with black PVD, while the fixed steel bezel is rubber-molded in order to provide the most contrasting display of the Arabic numerals placed at “10”, “20”, “40” and “50” minutes and, again, make the watch look even sportier.

Skeletonized dials rarely blend seamlessly with expressly modern-styled bodies, however, this one is almost in perfect harmony with the rest of the watch. This is, perhaps, thanks to the clean, geometric forms of its main 12-pivot central bridge, as well as the six chambered satin-finished seconds bridges that not only serve their main function but also decorate the dial.

I am not sure how much Pierre DeRoche is going to ask for it, but the watch is definitely hot.

By the way, here is an official computer rendering that depicts another member of the family (the TNT Grandcliff,) but gives you a good idea of how the retrograde complication actually works. Enjoy.
