It’s also the spreading effects which are very, very important

I thought in watch repair spreading was considered to be very very bad? This is why you have products like  Epilames found at the link below? Not that it's normally used by most hobbyists as it's too expensive.

Yes, that’s exactly correct. It’s important that they do not spread. Mineral oils can be awful for it.

extending service intervals by way of advanced lubrication

I would be really curious to see the press reference that references lubrication? It's my understanding that the watch companies are trying to get away from lubrication using stuff that does not require any lubrication at all.

Yes. You do not want any spreading. There are many reasons for why it can happen, such as unclean surfaces (especially if there is a minuscule residue film of oil). It effectively causes as similar effect to the oil drying out as it just continues to migrate away from the bearings. Ironically, over-oiling can also cause this effect too if it creates a pathway for the oil to run away to. I've seen that on cap jewels where the oil has spread across the entire chaton and jewel hole, only leaving a thin film everywhere.

I don't recall exactly where I saw it. Some manufacturer's announcement about a new movement. It was within the last month or so that I saw it. It was one of the larger groups, but I don't recall exactly which one. Sorry I can't be more specific.

Finally, if anyone recognises this early 10.5’’’ movement, I’d love to know. I have suspected an FHF but not sure. All train wheel bridges are separate (unlike those designed to look separate).

If you have suspected this to be an FHF 1146 I think you are right.
There is a spring new at Cousinesuk you could try out.

[mention]HSL [/mention] That’s probably the closest match I’ve seen yet. Either the FHF 1144 or 1146. Probably an earlier version of one of them as both plate sides differ slightly from mine. Thanks for pointing this out. Appreciated.
