It looks like the backdrop is single wood piece, so it would have been carved and the colored strips are glued into the little arcs? Not tiled, so would have had to go all the way around. Or it is a sticker.
RE: How was rosette executed so perf... (in reply to Ricardo)
I suspect there’s black mastic* involved. In other words, the black background is done last. Just guessing, but the circles could be prepared as cylindrical sticks and then sliced. First step would be to glue down one colour’s circle as a whole into a channel cut in the backing surface (the top), chisel out two cross channels for the next circle, which would also have to be cut in two places to allow the appearance of interlock with the initial circle, and glue down the second color. The final circle would require the most cuts. Then once all the circles are glued down, fill in the background with black mastic or some other kind of viscous filler (epoxy?).
Just a guess, in truth I have no idea how he does it. His workmanship is impeccable and reminds me a bit of what my nephew is doing (he’s just starting out but has extensive cabinetry experience).

I bet you nailed it. Probably intarsia using CNC to route the back piece and the pieces to be inlaid are regular lines bent into the channels. Or a sticker. Or maybe what RobF said.
It looks like all the arcs are the same length, so that's one simplification, perhaps.
Hey, maybe we should have a challenge to see who can duplicate it. Oh, wait, I don't have a CNC machine. Maybe I need one.
If it’s a wood field instead of mastic and CNC is involved then I suspect it would still have to be done in three stages. Otherwise it would be too much of a pain in the butt, way too fiddley. The presence of minute amounts of dark field between the interlocks does suggest either the use of CNC or a form of mastic filler, however, or maybe a combination of both.

You don’t need one. You already make beautiful guitars.
I recall seeing haw this was done. It wasn’t that complicated, just looks imposable ;)
Part of me says, oh my that rosette will make the guitar sound better than the others.
But here I am spending hours and hours exploring old school marquetry cause, dog knows why, my rosette style was labor intensive enough already.
But gosh, they sure make my guitar sound better…

Thanks so much, Rob. Actually, it kind of bothers me that, according to Guitar Salon (they told me), people buy guitars based on their looks. I'm more interested in them as musical instruments. But it's fun to know how to do crazy things like this rosette. A long time ago I tried to do something related, using the traditional method, and wasn't happy with the result.
