AP `15400 AR crystal

[mayzewin]

Quick and pleasant dealing with Prof for my black 15400's crystal. Will be utilizing his services again in the near future.

Hi,
Did you install a double AR crystal on your 15400, or single AR coating ?
Would you be able to provide any picture by any chance? I am thinking of doing the same mod to my ZF 15500... curious to see the difference before I pull the trigger! :-)

Do Gen AP 15500 have double AR?

Gen doesn't have 2xar, but since the OP stated that his rather quick experience, I'd assume he sent his watch to prof for installing a readily available xtal which is probably the 2xar prof has in stock.
