Thanks for the tip, what did you use to insert into the two notches of the retaining ring to twist it loose? Someone mentioned to me pair tweezers or the ends of a snap ring plier works.
What did you use to remove the plastic retaining ring on the back of the Z61 tailcap and did you have to apply heat to the cap in order to loosen the ring? This is my first attempt a disassembling a Z61 tailcap and don't to mess it up.
Can some explain to me what's this boiling process I've read being mentioned in many bezel/lens removal threads and is it a necessary process to get the job done? Thanks
