One of the greatest recent reviews, nicely done. My grail. My first rep was Mary SMP300 with aluminum bezel and correct HE valve position. Sadly I was reckless with it, damaged and eventually lost it, then just moved on. Now miss it so much. I see it is of course no longer available, a pity only 5 digits Rolex are popular to produce nowadays. Also MKS (or MKF) V4 with closed caseback is not available too. Love close casebacks not only for being closer to gen, but also ability to simply swap movement if something goes wrong, like a2824 or similar. Probably will buy all blue ZF though, its a stunner for sure.
