Some folks say that FPJ Repeater is not as loud as Patek.
One nneds to consider thar this watch is so special because how very thin it is at only 8.5mm and it is quite remarkable that F.P managed to create a minute repeater caliber 1408 that is only 4.5mm thick.
I guess it is expected then to have a little bit of the trade off. You have a thicker watch you will have bigger Echo and a bigger sound. The FPJ RM is thinner, so it is not as loud.
I never had a chance to hear Patek repeater but I still own JLC Reverso Repeater. It is a preety small watch and I would say that they are at the about same level when it comes to the loudness,....(FPJ being significantly more *musical* and somewhat nicer sounding)
