I think most collectors will be familiar with the Jaeger-LeCoultre Master Tourbillon line; it is one of the most accessible entry points for this complication, and finished to a higher level than JLC’s already excellent regular pieces. But it’s unlikely that you will have ever seen these particular examples, from the Haute Joallerie and fine art lines – special pieces that are made in extremely limited numbers and never seen outside the boutiques. Much more artisanal handwork is required than normal, from the cutting of the rare stone dial to inlaying of the diamonds to guilloching and enameling the dials; I personally much prefer the non-jewellery versions, but the aventurine stone dial has great depth and ‘pop’.
