Automatic chronograph watch movement Daniel Roth DR207.
The base is a Frédéric Piguet 1185 column-wheel chronograph movement, 40 hours power reserve, cadence of 21,600 A/h, 35 Jewels, adjusted in five positions, ca. 24.6 mm diameter.
This movement is used in some very expensive Daniel Roth watches (Ellipsocurvex Perpetual Calendar Chronograph). Similar Frederic Piguet base movements are used in luxury watches like Gérald Genta, Blancpain, Vacheron Constantin and others.
The movement was ordered for a watch service and was never used. The article is sold “as is” – any other parts that are not described or shown in the photos should be considered as not included with this movement.
