Hi, can anyone help me in my decision to purchase this watch? I have a chance to buy it locally for $2500 USD and am trying to figure out what the value is. The case reference is 1163 and its clearly visible on the case between the lugs. Also the serial# is clearly shown as 277866. When researching the watch I realized that is a reference 1563, which is the caliber 15 movement version of the Heuer 1163, and that some of these had 1563 on the case and others had 1163 on the case (like this one), even though it is a 1563. I've read on forums that this is true that some of these 1563 actually have "1163" on the case between the lugs. I can't seem to find an exact match or comparison online. I see a very similar watch but I don't see one with the exact hands that this one has. Also I've noticed that the crown is not "Heuer" signed, so it must not be original. I would greatly appreciate any insight from anyone that know this Heuer Autavia model. Thank you!
