How do Atmos clocks work without winding?

An Atmos clock operates using a hermetically sealed chamber filled with a gas and liquid mixture that expands and contracts with minor temperature fluctuations. This perpetual motion mechanism winds the mainspring continuously. Because temperature changes are constant in any room, the movement remains powered indefinitely without human intervention. This engineering feat makes these models highly sought after by collectors.

What maintenance do these mechanical clocks require?

Mechanical timepieces benefit from periodic professional cleaning and oiling to ensure the gear trains operate smoothly over decades. Proper placement away from direct sunlight and drafts protects the exterior finishes and internal balance. Perpetual motion movements should be handled with care and locked when moved to prevent damage to the delicate torsion pendulum. Following these guidelines preserves both the physical condition and the timekeeping accuracy.

How do I identify a 1950s piece versus a 1960s piece?

Clocks from the 1950s often feature classic round dials and traditional desk formats, sometimes paired with alarm complications or travel cases. Design cues lean toward restrained elegance with polished brass and clear glass. By the 1960s, aesthetics shifted towards bolder geometries, skeletonised movements, and varied case materials like lapis blue or rhodium plating. Examining the specific calibre numbers and styling helps narrow down the production era.

Where should I display a desk clock?

A desk or mantel clock performs best on a stable, level surface away from vibrations that might disrupt the delicate pendulum or balance wheel. Placing the piece where natural light catches the glass and metal highlights the design. Many collectors choose prominent positions on office desks, bookshelves, or living room mantels where the mechanical action remains visible. Ensuring a secure spot protects these intricate objects from accidental knocks.
