I just acquired this week a Seiko SVCS003 6R15A (with two bracelets) that had been sitting in the seller's drawer unused for some years. While the watch is beautiful, it is horribly inaccurate. As I am a newcomer to watch repair, I would like to know if it is possible to regulate this watch to acceptable performance, which I would try to do myself, or if the huge disparity is indicative of some other, much more expensive problem. Apologies in advance if this is not an appropriate location for posting. Appreciation for any and all comments.
