The problem with BP is on their Subs, the implementation with a 28XX is lousy.
These are mine. On the SD4K they got the date font and window position correct by using an overlay. Mine has a 2824, which I replaced with a gen ETA. But if you look at the BP submariner with 2824, you'll see the date position is 2mm too far to the right, and both the shape of the window and font are wrong. I don't wear the Sub, as its quite obviously wrong. I've been meaning to turn this into a LN no date for ages - just haven't got round to it yet...
It used to be that cloned movements were crap, or difficult to find - but thats not the case anymore.
