and congratulations to M4 for being the inaugural moderator of this forum.
Here is my Kalpa Hebdomadaire, plus its distant second cousin Chopard LUC with 3.97 caliber since Michael Parmigiani was heavily involved in the design of this caliber.
Also while the Kalpa is longer and bigger than Chopard, it’s more comfortable on me as it hugs my wrist better and a bit lighter for being in SS instead of WG.
