A near perfect example of this spectacular timepiece! I bought it new and it's been sitting in my collection virtually unworn. I've worn it maybe 2 or 3 times. I just have too many in this category so this one needs to go. I inspected it closely and I can't find a mark on it. It is 99% to my eye. Please view the pictures and decide for yourself. I'm happy to send more to anyone interested. Score a virtually new watch for less money! It includes all boxes and documents it came with new. I only accept PayPal and price includes fees and shipping!
Thanks for looking!

* The Altimeter expresses altitudes as relative altitude by converting pressure changes measured by its barometric sensor. The readings will vary with air pressure changes due to changes in the weather or other natural phenomena.

* Temperature reading is affected by your body temperature, direct sunlight, and moisture. To achieve a more accurate temperature reading, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture and sweat from the case.
