In the old days, watch movements were fitted with precious rubies to reduce the friction and wear on certain key metal components in them. Today, those precious rubies have been commonly replaced by manufactures by synthetic rubies that do the work, but that don't look merely as beautiful. The new Christophe Claret Maestoso ref. MTR.DTC07.000-020 presented at Baselworld 2014, is actually one of the few watches in the market that features actual precious rubies on its fascinating movement.
