Out of curiosity seeing as how I do not trust artificial intelligence for variety of reasons. First eBay and then generic ones. But it would seem odd that you would make a generic screw blue if they were blue in the first place? https://www.ebay.com/itm/235878965719 https://www.jewelerssupplies.com/blue-screw-for-date-indicator-generic-for-rlx-3135-R3135.5600.html Here's a video when he takes the dial off some of the screws definitely look blue?    

I‘ver never seen a fake Rolex with a free sprung balance and micro stella regulation.

I do not see the purpose of the holes extending into case. Pins from a screwback opener will catch the edge of the holes.

Hi Mike,  Welcome to the forum. 

No...They would line up for a double pin opener but the pins would have to be .5mm or less
