This is a vintage watch from Universal Genève, circa 1970. As you can see in the photos, it's a very thin watch, which I believe is made possible by the micro-rotor movement. I have confirmed that similar items are being sold. This item has no issues with the crown slipping and can be handled normally. Getting back to the item itself, I won this at Yahoo! Auctions about three years ago, and it seemed that the automatic winding mechanism wasn't working from the beginning, and I think that's actually the case. That's because it's a center-seconds watch, so it's hard to tell... When you shake it, you can hear the rotor spinning and feel a slight response. However, it seems that this model was said to have poor winding efficiency from the time it was released, and I heard that the rotor's rotation slows down when the mainspring is fully wound. Therefore, micro-rotors often use precious metals like heavy gold or platinum, but this item doesn't seem to. So, is that why the winding efficiency is poor? As mentioned above, I can definitely see the rotor rotating, so I honestly don't know whether that's connected to winding the mainspring... I've resigned myself to using it as a manual-winding watch. The hands can be moved by the manual winding mechanism and the crown, so as I mentioned before, I've been using it as a manual-winding watch. This watch is a center-seconds watch. Therefore, without a second hand or minute markers, I can only estimate the accuracy, but it doesn't lose more than 60 seconds per day. It's accuracy that I can't believe is from a watch that's about half a century old. Whether the previous owner polished it or not, There are some minor scratches, but the case is surprisingly clean for something that's about half a century old. I don't know if the crystal is glass or plastic, but It's clean with no cracks. The leather strap has been replaced with a new one for this listing. As mentioned above, please understand this as a vintage item and with no returns, no exchanges, and no cancellations. I have something else I want, and I'm reluctantly letting go of this item to fund it. I hope you will consider purchasing it.
