Pierre DeRoche TNT Royal Retro Sapphire

In 2009, Swiss luxury watch brand Pierre DeRoche introduced a world first with the launch of the TNT Royal Retro and its six retrograde seconds mechanisms. This watch made a significant impact, and three years later, the brand announces a make over model: TNT Royal Retro Sapphire featuring seven visible sapphire bridges.

The now entirely transparent movement unveils yet more of its mysteries, further revealing the originality of its spectacular complication.

The association of sapphire and titanium, two extraordinarily hard materials, gives a whole new expression to the TNT Royal Retro Sapphire. This sleek, masculine and sporty timepiece will be available in an 11-piece limited edition.
