I have been silently enjoying the discussions here, and have decided to take the first step into VC ownership. I recently graduated from college in the States, and consequently do not have a vast disposable income but I mean this as a graduation gift to myself. In my search for an affordable VC I came across a piece (ref. 31039/000J-3—images below). I put down a deposit not being able to spot many red flags on my own with regard to its authenticity, but I wanted to get the community's expert opinions. (I am open to suggestions to get other pieces as well.)
One glaring red flag that I might have overlooked is that the reference number on the listing did not match any results on the search page on the official VC website. Another is the claim that the warranty papers retain an open date, despite the watch being preowned.
Anyway, here is the Chrono24 listing and then a more detailed listing on the purveyor's website—no photographs of the movements as of now. The purveyor does have quite a few other VCs listed, with a wide range of production dates, if that provides any useful background.
Thank you all in advance, I will be checking here regularly.
