Really? It was part of an auction? Wow, I did not know they accepted such bad quality watches. You need not open the caseback to know it is a bad replica. Where does one start? Dial is completely wrong, does not have the Arktos name, it should not be carbon fiber, has minute markers which should not be there and also says TSMT when it should be LSML. Subdial is way too close to the center. Indeces are wrong, steel surrounding the numbers and are too long. No chapter ring just a steel rehaut. The sticks on the bezel are too long. The caseback, although having similar engravings and markings, only uses the standard OP caseback. The Arktos caseback structure is different.
All in all, you would do better to get even the low end PAM 092 from the TDs and you will get much better quality. I hope you got what you paid for in the other items in the collection you won, your rep certainly does not add anything to the value.
