Louis Erard and Konstantin Chaykin Present the First Tourbillon Edition in Their Collaboration

A few days ago, Louis Erard and Konstantin Chaykin unveiled their third collaboration: the Time-Eater III, featuring the famous one-eyed monster design, an edition the two brands described as “the final bite,” which some interpreted as a hint that it would be the last in this distinctive partnership.

However, the collaboration didn’t end there. Today, the two maisons reveal a remarkable new addition: the first tourbillon regulator watch born from their joint efforts, a significant leap that takes the partnership to new heights, all while preserving the creative spirit that sparked it.

Corundum

Corundum

Corundum is a crystalline form of aluminium oxide typically containing traces of iron, titanium, vanadium, and chromium. It is a rock-forming mineral. It is a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. In watchmaking, corundum is used to create the front and back glass to protect the dial or various parts of the watch from damage and scratches, as it is one of the hardest materials after diamond in terms of hardness.

Additionally, corundum exhibits high chemical resistance and good transparency, making it an ideal material for glass manufacturing in watches.
