Jaeger-LeCoultre launches an Atmos Regulator clock in a limited series of 28 pieces created for luxury brand timepieces Alfred Dunhill. The design was inspired by Dunhill's lighters and cigarette cases from the 1930s. The front of the shelf is inlaid with black stingray leather, a reference to Dunhill’s heritage in luxury leather.

The 242 piece caliber 582 movement is powered simply by small changes in temperature in which a change of one degree will give the clock enough juice to keep ticking for 48 hours.

The Atmos Regulator is available now at Jaeger-LeCoultre boutiques and retailers at $70,600.
