Armand is endeavoring to undertake an incredibly challenging project - the development of a tourbillion that incorporates a one minute remontoir that lets 3 discs for a jumping hours and minutes display.
This is a remarkable project and I'm excited to watch it unfold. It is also a great opportunity to look into the design and development process.
Interestingly, Sartory Billard is primarily known these days for the current SB04 and 05 models. From the article it seems the previous models didn't have widespread appeal. But I think Armand may have been a little ahead of his time with those designs. With the increase in attention in independent brands over the last few years, I actually think those would be very popular.
But there is also a definite move by many of the smaller independents to move upmarket and this is an enormous step for Armand.
Knowing his dedication and willingness to work, I'm certain it will be a success. I look forward to following the journey.
