This is what Ziggy said about it on RWG:
"Personally I don't buy any of it, marketing hype.
Truth be known, there were already a number of extra jewels in these models, at least in the latest versions of seconds at 6. I think 29 is actually too low a number, it's probably more like 34 or more jewels.
The problem has always been, and continues to be the design, you can put all the jewels you want in the movement, but when the gear sits in the jewel but is sitting flat on the movement bridge and rubbing against the movement as it turns, all the jewels in the world aren't going to fix that friction.
The fact they use 5 instead of 3 gears to get the seconds at 6, and one of those gears can never be jewelled since it sits in the center of the movement and has a ton of friction, means any upgrades are pointless.
Use 3 gears only for the modification, have all of them pivoted in JEWELS like they should be, and your problem is fixed. Easy, simple, but they don't seem willing to do what it takes..."
