Dial variations vary from Yellow, White and Rose with the exception of the ruthenium series. Cases were made in mostly platinum, with some rose gold pieces are very rare two tone cases.
What I find truly fascinating with the Resonance is the technology behind the movement’s complication and its execution. Having been attempted by many, Journe’s execution is flawless in my opinion, creating what has now become an icon for the brand. The resonance allowing self regulation of the two balance wheels, whilst being able to track two different time zones is an opportunity for the wearer to showcase both his taste in fine horology, use the watch in different scenarios and unveil ones inner nerd to anyone daring enough to ask how the watch works.
