Per WatchAdvisor Video - start from 18:30 -> Guido says a machine does something to the dial, I think he is saying some guilloche dials are made by machines. See YouTube Video below.

That’s the video I mentioned a few times, was too lazy to dig it up

But that video + looking at the dial with a loupe and I’m almost 100% sure it’s done with a cnc

I think that the definition of HAND MADE finishing is out of control

I think that the quest for the hand made is getting odd. In what way, if any, does the CNC guilloché diminish the overall value and beauty of the Tonda? Given the only undebatable fact that prices are all crazy, I usually prefer the best quality I can get... 

Breguet uses a rose engine in the same price range

And gets a much better 3D looking dial as a result imo. YMMV. Personally I think it’s a missed opportunity.

Many purists thought it was hand made

Now It looks CNC made. Watchmakers should always tell the truth, no more storytelling. Then a customer is informed and free to choose

I couldn’t agree more

It’s not a matter : of aren’t we nitpicking here? Or “diminishing the over value. ..” handmade guilloche has a very specific and well understood meaning. If you say it, you are saying in effect, …by a rose engine. It’s not about diminishing the overall va... 

What I take from this is Parmagiani is playing fast and loose with certain dial-making terminology.

I agree that when you say "hand-turned" you are talking about the use of a rose engine. It appears that Parmagiani does not use one-at least in the making of that Tonda dial. I guess that the way the brand uses a cnc machine is not strictly "stamping"-it'... 

Clarification from Parmigiani today

My question sent today to PF: On the Milano Blue Chronograph, is the dial guilloche executed by hand or by CNC? The reply from PF customer service: "The dials of the Tonda PF are hand executed. The dials of the Tonda PF Sport are machine executed." M4

Right - as noted above, I think there are many ways and methods to create a

Guilloche dial - CNC and a rose engine being but two methods; but the creation of guilloche dials are not limited to those two methods {stamping, hand hammering, chiseling, maybe lasers, etc,) I think Parmigiani should let us see what “hand executed” mean... 

15202 dial was created partly on a rose machine and that’s one of the reasons I got one; see below..

youtu.be youtu.be Also the way AP industrialized the making of the bracelet is an achievement see below youtu.be If it wasn’t for the crown coming out I’d still have it ...  

One more interesting thing to note about manufacturing the Royal Oak

 
By: K-Lo : January 22nd, 2025-19:28
In 1972 I heard AP did NOT have the machines to finish the Royal Oak to Genta’s designs; so, the models shown at BaselWorld were in white gold because gold is softer than steel and could be finished easier…

The comments on the video are funny and also address the misuse of hand made for both dial and bezel

At this point I assume any / all of the big brands do little if any skilled handwork (which is fine) and ignore the false or misleading marketing (not fine but the norm). My hope is that the big brands return to providing great value like JLC used to rath...
