I got the ROL054 http://www.silix-prime.com/index.php?main_page=product_info&cPath=116_205_213&products_id=1972.
The caseback was not the one shown on the website. I got the one with "ROLEX OYSTER - Original Gas Escape Valve" and I got a gas escape valve in the case + a crystal (that I changed) without date magnifier.
They have quite old pictures on some of the watches, so try send a picture of what you want instead and the should be able to find it.
Bought a very cheap 1665 rep from Silix with Asian 21J movement.
Did some minor vintage mods on it and I think it turned out pretty nice!
I know it has several flaws, but for the money and effort (low) put on the mods I find it a great everyday watch.
Bleaching the bezel insert, some softening of the edges and a new acrylic crystal from Sternkreutz. That's all.
Thanks for the kind words!
Today a very cheap 1665-ish DRSD thing with some vintage mods and new Sternkreutz acrylic crystal. See other wristie thread.

Seems that there are no more available at the time. Sure there will be up more soon.
