ogladio you are really informed about the 6542 project, really good
i contacted Silix, and i ask to him if he can find for me only the case of rols176.. he reply to me he can.. but without the bezel ring.. it's the reason why i asked about an aftermarket bezel..
in theory yes my budget is limited around 1000$
i find this dial.. http://www.vintagewatchmaker.com/product-p/d-05.htm it's around 450$
in the same site there is the bezel... without insert around 300$ and with bakelite insert 550$...
but i don't know if it fit on the rols176case...
