Rotonde de Cartier Astrotourbillon
At SIHH last week Cartier launched the new Rotonde de Cartier Astrotourbillon with their new manual winding movement, Caliber 9451 MC, designed and created by Cartier watchmakers. This unusual movement is the product of 5 years of development at the Cartier Manufacture in La Chaux-de-Fonds. The Astrotourbillon’s carriage is driven by the third wheel of the gear train. The pinion of the escape wheel rotates around a fixed seconds-wheel (the fourth wheel of the gear train) in order to drive the escapement. The carriage has a special rotational axis, as it is positioned at the center of the movement. This requires a different gear-train design, from the two barrels of the movement through to the display of the minutes and hours. Another feature, responsible for the striking visual effect created by the movement, is that the balance staff and escape-wheel staff are not on the same rotational axis as the carriage. They are located to one side of the carriage, in linear alignment with

Need Your Expertise on a 2008 Sub 16613LB Rehaut Serti Dial
Hey Guys, I wanted to get your opinions on this watch, it is a 2008 Model which does not include the papers/documents. It does include a 3 year warranty and the box. The seller is asking for ~$10000, does that seem reasonable/good buy for this exact watch or should I pass on this? Thanks in advance!! https://watchchest/rolex-submari...lb-rehaut.html
