I needed a caseback for a 16000 dj. The one on this watch was a little knockered. I posted a WTB and within a very short time I had 2 to look at and one is on its way and will be here in a few days.
Where else can you do that?
I realize it's not a rare part particularly and I could wait it out and find one on ebay but I really want to tidy things up and waiting for auctions and bidding and all of that....for a mundane caseback is well....you know.
