Any updates on this?
To be sure, there are ways to replace conventional hairsprings, but I can't name too many that offer real improvements. Aside from the fact that this Calabrese proposal appears to use non-repairable DRIE parts, there's also a major burden of proof to be provided before the advantages can be considered against the disadvantages.
Zenith and Frederique Constant have their own alternatives to the hairspring, but the benefits there are debatable. Even in the case of Zenith with the Defy Inventor, all of Guy Semon's genius and LVMH's money couldn't make it work quite as advertised. Has Vincent Calabrese bypassed all those challenges while operating solo?
Best,
Tim
