Thanks!You did a nice work on the lugs
The Silix cases I worked on had no retaining ring ... the rehaut had a groove and the bezel was held in place on with a "paperclip spring".
So could you share a pic without the bezel to check if it's the same assembly ?
If you are in the same situation, you can make your own paperclip spring from very fine metal wire ... I'll search for one and share pics.
About the crown you can order one from Athaya ... 7mm brevet crown and tube ... but you'll have to remove the existing tube then drill and tap the casing.
You also will need a stemp extension from Cousins ... Ø0.90 - Ø1.20mm (Tap 9 to 12) ... to make the 2824-2 stem fit on the Athaya Brevet crown
Regarding the bezel, I do recall there was a sort of thin metal wire that was shaped like a Royal Oak bezel with many corners. The insert itself was just glued or I think friction fitted to the actual bezel itself.
I was checking costs, and having to buy all new parts for the case set really does add up and I'm now considering just getting the Raffles case set.
I also tried sending you a message but realized I can't as of now. I guess we shall be waiting for your banner to be lifted. With this said, would a dial like this be possible from your end?
