42 mm Explorer II Case Back Die Size

[willee]

Hope maybe someone can help me of what tool to buy.

I am looking to put a sapphire case back on a 42 mm Explorer II. What size die do I need to remove the case back?

The factory case back takes a 29.5 millimeter die. I have no clue if the aftermarket sapphire unit is the same.

Did you put on a see through case back?
