Hey there! For sale is my Omega Speedmaster Day-Date or ‘Triple Date’, reference 3520.50. This is an automatic 39mm speedmaster using a movement based on the Valjoux 7750, making this an integrated chronograph, unlike the more common automatic speedies you might find. The watch is in good condition. The pictures and video will speak to that, but I would be happy to provide any additional information. Internally, the movement runs like a top at -6 seconds per day. At the end of the video is a short demonstration of the chronograph starting, stopping, and resetting as it should, and triple calendar advancing properly. The watch will include the international warranty card and a few links to size the bracelet up to the most common sizes. I can resize it upon demand.
