Thank you very much for the information. It's the lume beneath the hands and on the ends of the hour barons that really attracted me to the watch, but I also understand that the 30J movement is a work of art in its own right.You could try to find it under the reference number 8305-1000 (M77 Sealion) of 8305-1010, that's the same watch, only no Sealion on it, and reads Seikomatic-R. I got both of them...
But I would not want a blue dial, because it would affect the luminous effect on these watches (hidden lumious effects!)
Really lovely work!
Thanks for that, and the link, I'll read that tonight....
If I ever decide to move it on, I'll try to track you down to give you first offer.
