As I stated, I cannot vouch for the authenticity of the pieces in the video and thanks for your warning regarding that. I've also described my unpleasant experience with my 5370P, as well as that of my friend's brand new watch's caseback that completely fell off upon cutting its plastic bag, and that of Mr. Sam Wan's, be it oil leak or not. These are quite serious issues. My love towards the brand remains, and I am always thankful to my AD who allocates me with the latest pieces. It is exactly for my love of the brand that I wish similar negative issues could be minimized. The video was shared to raise such a concern and I for one now always take a close look at my allocated pieces with a loupe for any issues, rather than simply being overwhelmed with joy with the allocation and quickly paid and left without a detailed inspection as I did in the past.
