I now understand your confusion. I went to check the JTime website this morning and found that it's no better than when it first launched. They have a close relationship with ZZF, but there's no "ZZF" option in the factories list when browsing for Rolex. Then, as you say, when you find them, the only reference to the ZZF is one with an ETA clone or "A3135".
You'd do much better contacting Li directly - email JTime and tell them what you want, then you can discuss it one to one. It's far easier.
Yes, the 16610 is a watch to LOVE, and I prefer it over the 116610. The jury is out on the new ARF until customers get them and start reviewing/discussing them here.
You could hold out for an M2M deal on a JF, they come up reasonably often and have often been modded nicely.
Be patient and hunt down the absolute best ever the TC. I scored 2 but took 3 years to do it lol.
