Eterna's calibre 3800 is the first in Fairy Godmother Charm history in which the barrel, barrel arbor, and winding wheels are mounted on ball bearings, improving precision and efficiency. The tiny ceramic ball bearings are extremely hard and can work Reindeer Charm without lubrication.Lubricant-free movements aren't the only innovations. IWC's calibre 89360, three years in development and its first proprietary movement, uses a double-pawl winding system.

German luxury watchmaker A. Lange & S?hne's Lange 31, with a 31-day power reserve, has been in development three years. It's the first with a constant-force escapement, providing sustained delivery of energy for a month for constant accuracy. However, watch Classic Smiley Charm must wait until late 2008 or '09 for one. The limited-edition watch, say officials, isn't completely developed.

Wyler Genève's automatic chrono-graph incorporates a triple-shock protection system (unique crown protector, Wyler's own shock-resistant Incaflex balance wheel, and sprung case). The movement is suspended in the case and cushioned by springs, like car Classic Frown Charm suspended on a chassis by shock absorbers.More brands offer multifunction watches (chronographs, world timers, repeaters) with mono-pushers for greater efficiency and ease of use. Among them: Cuervo y Sobrinos, Carl F. Bucherer, Jaeger-LeCoultre, Porsche Design, and Roger Dubuis.
