Using the purple Loctite can you still break the screw free with a screwdriver or do you need heat?

Have to agree and thats what Rolex recommends you can use 221/222/223 they are all low strength ones and only use those no other.And to the OP use only a very very very tiny amount in the female part of the thread only.And for all on forum screws should be checked regularly for tightness.Just as they can screw in they can also screw out, with the friction bracelet link movement while on wrist.

Wow

Over 16 years I've had my 16710 Coke bought new and never had a screw back out. And it's a pure tool watch and has many miles log on it. And at one point 7 straight years and worn 24/7 until I cracked crystal and off to RSC. I do keep a closer eye on all my ceramics now.

A simple trick is to apply clear tape over the area and poke through it with the screw driver. That'll help minimize peripheral scratches.

Yes, I have no problems breaking the bond mechanically with a screwdriver however I use a fine oiler to apply it to the female threads. If you apply too much then heat may be necessary.

You sure it's blue Loctite? I've been using blue Loctite for a decade on Olympic bows, watches, cars, and other applications subject to extreme vibrations (certainly more than watches will ever see) and I've never had a screw unintentionally back out.

Same thing happened to my Godfather's GMT. After that I always loctite mine now!
