I'm very interested in this watch. It's listed as a Sinn Edelstahl Automatic Chronographer, 3115154. This movement looks like an ETA 7751. It seems that some siblings are selling watches that their recently-departed father had in his collection but $2,495 seems a bit much as the first thing I would do upon purchase is have it serviced even though it appears to have been little-used. That said I'm not exactly an expert so I'd appreciate some input as to what members think is a fair price. Thanks in advance for your input.
