Now, I've got the old tube out of my MBK 1680 Sub and am looking at fitting a Cousins or gen replacement. I can't seem to find a tutorial on what I assumed would be a fairly well-documented task, so I'm asking for any advice and data from anyone so I can compile a guide that will serve all the new owners of these iconic replicas, as we're about to have an influx of members with these watches thanks to the Group Buy.
So, I'm after any information and experiences, in particular with information about what crowns, tubes and tools to use. In discussions with The Zigmeister, I've learned that maybe the Cousins tubes are better than the Genuine Rolex parts and that I need a 7mm Tap. Discussing tapping the case with Mrs Pugwash, as she has way more experience with serious metalwork than I, she expressed concerns over the amount of metal I'd be shaving off if I needed to drill the current threads out prior to tapping. Does anyone know anything about that?
What I shall do is collate all the info presented in this thread into a tutorial that covers crown guards, tubes and crowns in a convenient readable photo-rich article, so please help the community and share what you can, be it links, advice, pics or questions.
