I have been very close for the past 3 years at acquiring one. The Tonda GT chronographs almost got me, but there was always a detail that held me back. Extra writing on the dial, the style of a counter hand, the color of a date disc, etc. In older days of buying, I overlooked these kinds of details. I am much more particular now.
The brand relaunched the Toric collection this year. There are some FABULOUS older models that can be found at reasonable prices, although I suspect the overall attention on this brand will bolster the secondary market too.
But I do feel Parmigiani's overall quality and level of finishing is second to none, and even on the older pieces - many of which have polarizing, quirky details - these traits are quite apparent.
Happy shopping!
