I got the UBF grey dial about 6 months ago I would guess. As someone on this page posted, I also had a dial that was a bit offset and I had to release it (Puretime). Puretime gave me a little push back about it but ultimately let me get a different one where it looked pretty spot on.
My only complaint is that the sometimes when setting the time, the watch won't "restart" when I push the crown back in. Sometimes I have to do it a dozen times and shake it a little and try moving the hands around a lot. One time it just wouldn't restart and I gave up and just tried again a week later and it was fine - maybe it was a temperature difference or something. In either case it's pretty finnicky and I gotta mess with it maybe 10% of the time when I set the time.
I got a 2824 with the premise that i could throw a "real" 2824 movement in there whenever the original broke. However I probably won't bother with this grey dial one because while I like the watch, I don't plan on wearing it with any great regularity since I've grown a little bored of the grey dial. In retrospect I would have preferred to get a blue dial, and these days I'm actually more interested in the white dial. I'm glad I'm getting replicas before buying a gen because I'd hate to spend $6k on a watch and get bored of it in 6 months. I did the same thing with my black submariner rep - got a little bored within 6 months.
These days i'm actually looking at getting a gen grand seiko (has to be gen I suppose, no reps available). And a quartz model, too - I'm a little tired of having to set the time and date these days and I don't wear my watches often enough for them to stay wound. Upside is that their quartz models are only like $2k used in good condition. Downside is that their quartz models have pretty boring dials. It's a shame they don't have the cool textured dials on anything but the $6k+ spring drive models
