How do Atmos clocks work?

Atmos clocks operate using a sealed bellows containing a gas and liquid mixture that expands and contracts with temperature fluctuations. This mechanical breathing motion winds the mainspring automatically. Because temperature changes drive the system, these clocks require virtually no human intervention to maintain power. A variation of just one degree is enough to keep the movement running for days.

What is a carriage clock?

A carriage clock is a portable timepiece fitted with a handle and glass windows that reveal the internal escapement. Travellers originally carried them in protective leather cases during the nineteenth century. Over time, these utilitarian travel items evolved into decorative desk and mantel pieces. Swiss makers adapted the traditional format into miniature versions and luxury statement objects.

How do I wind an eight day clock?

Eight day clocks require manual winding approximately once a week using a matching key inserted into the dial or back plate. Turning the key tensions the internal mainspring. Care must be taken not to overwind the spring past its natural stop point. Regular servicing helps maintain accurate timekeeping across the full duration of the power reserve.

Are skeleton clocks fragile?

Skeleton clocks expose their gear trains and delicate escapements directly to the open air, lacking the protective enclosure of a traditional dial. This exposed construction requires careful handling during placement and cleaning. Displaying them away from heavy foot traffic or direct sunlight protects the intricate brass components from dust and accidental impacts. A glass dome is frequently used to shield sensitive movements.
