Automatic chronograph watch movement Daniel Roth DR101.
The base is a high grade Girard-Perregaux GP3080 automatic chronograph movement, and is used in some expensive Daniel Roth watches (Masters 18K Gold Chronograph, Numero 012, Abyss, …).
Cal. 3080 is based on Cal. GP3000 and shares that movement’s narrow 23.3 mm diameter and it beats at 28,800 A/h. Cal. 3080 measures 6.28 mm thick, has 38 jewels, and a 36 hour power reserve. It is a column wheel design with small seconds.
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.
