Full set. Original box, cushion, tag, papers (December 2021).
I got this watch from the first owner who had been super careful with it. I did five classic stealth modifications on it (listed below), lubricated the gaskets and tested the watch’s movement and water resistance. Blacksmithmods provides a 6-month warranty for the watch.
