Here is a build based on the late JF series. What needed to be done was mostly recessing the crown seat and cutting the bezel smaller by reducing the outer diameter. Other than than, usual reshape of the top of the lugs, redrill of the lug holes and reprofile of the CGs. Everything was aged roughly, then carefullt restaured. Bracelet was sand blasted and repolished as well. It's VERY smooth now, and without any grease of some sort... Crystal is swiss, dial is from Vietnam, crown is from Athaya, flat 4 insert is a cartel old stock aged and thinned like the gens to snap in the bezel without any glue leaving a clean step up around.
