he fine jewellery workshop of the Marteau family is renowned among connoisseurs far beyond the confines of Place Vendôme. Under its protective shade, three generations of jewellery makers have discreetly succeeded one another. Swarms of “necklaces, tiaras, mystery boxes, pendants…” created by the Marteau family for more than 60 years have left this place for destinations all over the world.
Jean-Jérôme, 31, who grew up within the walls of this family workshop, has carefully transposed this highend jewellery-maker’s know-how to haute horlogerie. He has succeeded in perfecting a special technique for setting stones in crystal that enables the stone or diamond to be fully apparent in all its shining glory at the centre of a domed sapphire covering a watch dial. This innovation spawned the first watch by De Tournemire, nicknamed “One stone, one tourbillon”.
Spreading its glittering rays from the centre of the watch, the stone (diamond, sapphire, emerald or ruby, from two to seven carats) sits above the tourbillon, the cage of which is set with diamonds. The tourbillon is flanked on one side by a retrograde jumping hours indicator and on the other by a trailing minutes indicator. This openworked timepiece exposes its superbly built and finished mechanism (hand-bevelled, mirror-polished tourbillon and barrel bridges). The 44.8mm case in 18ct white or 5N pink gold, or in titanium, is water-resistant down to 3 ATM and mounted on a black alligator strap, or alternatively on a strap of hand-stitched shagreen.
Whether it’s a jewelled watch or a jewel in watch form, this timepiece from De Tournemire is also an ideal subject for the decorative arts, coming in a self-winding Métiers d’Art version with an aperture display, or a disc display, or a display with two hands emerging from beneath the central diamond. A very broad range of expression providing scope for any number of variations, all sharing the common feature of a central diamond or gemstone.
