A collaboration among Jaeger LeCoultre, Les Cristalleries de St. Louis, and Hermès have produced the Jaeger LeCoultre Atmos For Les Cristalleries de St. Louis. With only one hundred and seventy-six pieces being produced, this stunning, spherical clock is a feat of metal and artistic crystal. Instead of relying on a battery or electricity, the Atmos clock is powered by an internal atmospheric mechanism.
