So.... this will be "half a guide" reasons at the end. ☹
Disassembly was relatively straightforward if a little tricky, if I was more organised and had the setup I should have made a video, so I will try to describe. Can't see how to re-order pictures so attached show (pic 3) the black tape peeled away, (pic 4) the screen with the tape removed, (pic 5). all the backlight parts.
I used a soldering hot-air gun to soften the glue, but I expect a hair-dryer could be used instead just as effectively, firstly on the screen itself and then used a suction cup to pull the screen away.
The back of the screen is covered in a black plastic tape, this is very sticky and needs patience to remove, again - used the hot-air to soften the glue and peeled away from the top holding the screen back as it peeled, this tore where it joined the LCD cables at the base, I was assuming I'd just cut a strip of tape to replace it with, but it you're careful you could probably re-use this.
Next I used tweezers to pull the black plastic cover away, this seemed to be clipped around the edges.
Next (more warming) and the thin white plastic sheet is glued around the edges and needs pulling away again from the top, this should come away with the solid clear diffuser.
Now all the parts ready to fit to the new screen in reverse, place the white sheet into the black frame with the black edging upwards, LED's down (pic 2), then clip the frame onto the back of the LCD (pic 1), finally clip the diffuser into the back of the frame and connect the ribbon cable into the screen socket.
And now the failure. Connecting up the new screen discover that the watch was indeed destroyed in the accident and is completely dead, so I can't add a guide to finishing the reassembly and confirming that the backlight works.
