Limited to only 100 pieces worldwide, and also to launch in the fall, the model is priced at $16,800. The most exclusive of the trio is a model with an 18k white gold case, with a cream-colored dial, on a black crocodile leather strap with tone-on-tone stitching. One Super Titanium model has a metallic black dial and is limited to 500 pieces worldwide the other has a blue-tinted mother of pearl dial and is limited to 200 pieces both will be released in the fall and are projected to be priced at $7,400. Two have cases and bracelets made of Citizen’s Super Titanium treated with Duratect for extra hardness.

The Caliber 0100 watches comprise three distinct models, each a limited edition, in cases measuring 37.5 mm in diameter and a svelte 9.1 mm thick.

Citizen’s engineers even built it to continuously monitor and adjust for frequency and temperature shifts once per minute, and to automatically correct the hand positions after the watch is subjected to shocks.Ĭitizen Caliber 0100 watch in SuperTitanium with mother-of-pearl dial (Ref. The successful result is a caliber that offers stable operation for up to six months on a single light charge, or eight months in its power-save mode.

Citizen also needed to develop power-saving strategies for the movement, employing materials and designs that would not only generate the much greater amounts of energy that the AT cut type crystal oscillators required but also render the entire mechanism sufficiently resistant to outside influences such as temperature variations, gravity, and age degradation. Instead, Citizen developed new AT cut type crystal oscillators, which vibrate at a frequency of 8.4 MHz, to replace the more common tuning fork-shaped oscillators used in most quartz movements the former type’s frequency is more than 250 times higher than the latter’s. Citizen’s Caliber 0100 is accurate to +/- 1 second per year.Ĭaliber 0100 achieves its ultra-high accuracy, Citizen says, without relying on synchronized data from satellites or radio-controlled atomic clocks, as do models equipped with Casio’s Multi-Band 6 Atomic Timekeeping technology.
