REBELLION Sapphire 540 Magnum Tourbillon

This exclusive edition of REBELLION 540 Magnum Tourbillon boasts an incredible rectangular watch case crafted out of sapphire.

Incorporating the state of the art diamond grinding techniques, the independent Swiss watch brand has extracted the eight elements that make up the transparent case of the 540 Magnum Tourbillon from specially cut sapphire blocks.

When taking up the insurmountable challenge announced by REBELLION TIMEPIECES, David Candaux had no idea what to expect.

The task facing him was to make a case of sapphire crystal imagined by the designer Eric Giroud, which would already be complex enough as it is when made of steel, gold, titanium, or carbon. Armed with all the confidence of a true pioneer, he produced something that qualifies as a world premiere.

Inside this virile timepiece is an extreme mechanism also developed by David Candaux, a recognized maker of movements.  The rectangular architecture of the REB T-14, with a double spring barrel, immediately catches the eye due to the large size of the tourbillon cage.

With its 540 tenths of a millimeter circumference and a diameter of 17.2 millimeters – hence the name of the collection, 540 Magnum – the tourbillon pervades the entire dial from its magnesium cage.

Another thing to note is the world’s smallest chain, to give legroom to the regulating ten-day power reserve indicator with conical gears.

In order to optimize the visual impact of this piece, the mainplate was made of carbon fiber. The high-tech materials used, like the special aluminum alloy, provide the mechanism with the necessary rigidity and lightness. They also offer some dark and racy views composed of subtle interplay of shadows and light.
