From the description, this is the TW best sub case that came after the WM9 v3. I don't recall which movement that watch had, but either a 2824 or 2836 can be serviced and repaired easily enough. BK had the dial and hands superlumed and with the gen parts, I'd consider this a $750-800 watch.
I recently looked at a JF 16610 for a project. At a cost of a little over $400, it was appealing, but then when you looked at servicing the movement, a new date wheel and possibly new reversing wheels, you were easily up over $800 in total costs.
