Bottom pusher fell off my Daytona!

I am quite OCD with my watches which makes this whole thing all the more surprising.

Will update again tomorrow!

It's not always about using the pusher, but rather, about over tightening the lock-nut against the case and causing stress on the slim pm pusher rod.

The lock-nut should just contact the case and not be tight at all... it just rests against the case to prevent the pusher from being pressed - it doesn't need any amount of tightening to accomplish this.
