This Franck Muller Cintrée Curvex Tourbillon Impériale reference 6850T is an exceptionally rare and exquisitely crafted wristwatch that exemplifies the haute horlogerie of the early independent era. Produced around the year 2000, this piece is housed in a 47 by 34 millimeter case made of 18k yellow gold, featuring sapphire crystals on both sides to showcase the beauty of its tourbillon movement. The guilloché dial is beautifully detailed, displaying Arabic numerals, blued steel hands and an aperture at six o’clock revealing the minute tourbillon with small seconds. The manual winding movement is hand engraved, finely polished and adjusted in five positions, demonstrating the meticulous craftsmanship for which Franck Muller became renowned in his early years. This example bears the rare serial number “00” which makes this watch extra special in terms of collectability. The watch is fitted with its original leather strap and 18k yellow gold Franck Muller pin buckle. It is accompanied by its original wooden presentation box (damaged) and has been preserved in excellent overall condition, showing only minimal signs of careful handling. A true collector’s piece, the Cintrée Curvex Tourbillon Impériale stands as one of the most sophisticated and desirable expressions of Franck Muller’s mechanical artistry.
