I brought a MBW 1680 to a watchsmith on Bowery to replace the crystal with a genuine 127 crystal.
well, you guess what. This guy put the crystal with the mag window at 12 minutes instead of 15. He also made a few scratches on the brand new crystal. Hell, the crystal is like $50.
He is either blind or he simply doesn't care. Quoted, "This is a fake and I don't understand why are you putting a new crystal on it. The original crystal looks the same to me. I actually spent 2 hours to put the metal part back."
I had to pay $25 to get my watch back and eventually I replaced a new crystal myself. I only spent 15 minutes.
Wasted $75!
