Romain Gauthier Logical One Secret Rubies timepiece showcases the art of gem setting with breathtaking vibrancy. No fewer than 185 invisibly-set, baguette-cut Burmese rubies totalling almost 10 carats grace the white gold cover, lugs and buckle of this mesmerising objet d’art.
Rubies are revered for their rarity, hardness and deep red colour. Burmese rubies, in particular, are coveted for their rich red hue, enhanced here by the terraced edges of the baguette cut.
While this piece’s18k white gold cover is set with 149 rubies (7.9carats), adorning the lugs area further 32 stones (1.1 carats). Even the 18k white gold pin buckle is sumptuously decorated with four baguettes (0.5 carats) to complete this masterful display of gem setting.
Inside beats the innovative, Grand Prix de Genève-winning movement of Logical One, which was conceived, developed, produced, decorated, assembled and regulated in-house at Manufacture Romain Gauthier.
More of the outstanding movement can be viewed through the display back; bridges and plates bearing a number of angles – including several sharp internal angles – feature rounded bevels that have been meticulously handcrafted. This type of eye-catching anglage brings out the inherent beauty of the components.
Logical One Secret Rubies is a unique piece.
