Having bought you the first images of the Pendulum movement, we can now share with you the very first photos of the TAG Heuer Grand Carrera Pendulum and its secret- this watch does not have a hairspring to regulate the movement- instead, it uses magnets.
This explains why TAG Heuer have joined forces with Tesla, because Telsa is not only the name of a car company, but also the name of the units of magnetic force- so a nice tie-in.
The Pendulum concept started about four years ago and is still in concept form- expect it to take a while for the technology to be ready for production, just as was the case with the Monaco V4 movement.
The case is PVD-coated and weighs in at an impressive 47mm- so much for watches getting smaller! The movement of the pendulum looks fantastic and there is a see-through window on the pendulum so that you can see the workings.
One of the key challenges with the design was ensuring the linear response from the regulator- this is relatively simple with a hair spring, but as you’d know when you put two magnets together, the magnetic pull does not increase in a linear fashion, but exponentially.
TAG Heuer have released a brief video to explain more about the movement:
