This is the Longines Master Collection Moonphase Chronograph L2.673.4.78.6 . This watch is the 40mm version and also features a Column Wheel. It also includes the Box and Papers and all authentication for the watch. I bought the watch on Ebay a fair bit ago and enjoyed wearing it. As seen it definitely has some wear and use. However, new watches have caught my eye and unfortunately my collection is getting larger, so I'm selling this watch. Service is somewhat unknown, though the previous owner said he had serviced it before selling it to me. Not entirely sure if true, but will still include that in this listing. Watch of course works and has no issues and keeps time well. As seen in the images and Timestamp, the watch comes with the Ebay authentication, and will send it with the watch. The watch again is pretty well used and has some scratches and scuffs, though polishing will make it look much better. The box and papers are here too however the box is slight damaged, one of the flaps is falling off and taped. The display box has only scratches, and the manual has no issues. The box also has 3 more extra links for the bracelet. Will clean the bracelet and box box before sending to make sure everything is as clean as it can be. Can also set the watch for you (setting the moonphase month day and date) so all you have to do is change the time if that's something you want as well. Looking to sell the watch for $2100 + Shipping, or best offer. Always willing to talk as long as the offer is not too low. Looking to use PayPal only for now. More safety for the buyer and seller and willing to tank the fee as long as the price isn't too low. Will ship quickly and safely and will insure the package in case anything issues happen. Happy to answer any question just shoot a chat.
