My understanding is that this is the classic 'Superlume' SD that was released last year with a much need pearl mod. The bulbous pearl was always the worst thing about the original release and the updated one is certainly an improvement.
I still think the crystal sits slightly too high and the SELs aren't the best, but otherwise it's a great value beater. I have one incoming from Sora - I'm hoping it runs on the same 21J high beat movement as the BP Sub No Date ceramic I got from him a few weeks ago. I've removed the annoying noisy rotor - it's now keeping better time than my gen Speedy Pro (that cost £2K!). QC pic for your pleasure...
