The latest watch from Christophe Claret the Christophe Claret X TREM-1, is an intriguing technical marvel.
Metal balls that appear to magically float inside two Sapphire tubes are used to indicate the time.

The balls have hollow cores and float due to magnetic fields, these are generated by two miniature magnets towed by silk cables and located inside the watch.

The silk is fine but braided and very strong, the type used in  reconstructive surgery.

The resistance of the silk was tested using a time-lapse system to the equivalent of 6 years.

The magnet, traditionally the enemy of mechanical watches in this case is a willing accomplice in the watch`s movement. The magnets are specialized and used in a way that don’t effect the running of the watch detrimentally.

A flying tourbillon adds further visual interest, it uses dual ceramic ball bearings to increase its resistance to shocks. It is inclined to 30 degrees to make it more visible to the wearer.

The Christophe Claret X TREM-1 is also readable in the dark thanks to SuperLumiNova strips placed along each of the tubes. The movement contains 419 parts and has a power reserve of about 50 hours. Double fold-out crowns on the back of the watch are used for winding and setting the watch.

In case you’re curious, the name “X TREM” isn’t used just because it sounds cool, apparently it stands for “Experimental Time Research Engineering Mechanism.”

I’m sure a lot of people will be eager to check out this fascinating timepiece firsthand at Baselworld which has just started. However if you cant make it check out the video below.

The price is 264,000 – 288,000 CHF depending on the materials used.
