Thanks for the comments. I'll try to answer all the questions.
The original watch was purchased in 2004 from Paul and the work was all done by Ziggy over a 3 year period. I got the dial used on eBay, OEM hands and crowns from Ofrei and with all of the mods complete, I still did not come close to the price of a used SMP. I know because I had looking at genuines before embarking on this path, which by the way, is much more fun
The genuine does not have AR but after putting on the OEM dial, I thought it deserved the Single Side AR treatment Chief does. It makes a huge difference and even a purist would be hard pressed to know it was coated - other than the anti-reflectivity
The OEM HE valve is operable although I have no plans for diving with this one.
