logical sparkle by peter lau from china

Logical Sparkle is a crystal wristwatch.

Its facets represent hours and minutes.
Hour group has twelve facets showing hours from 01 to 12.
Minute group has twelve facets showing minutes in every five-minute format from 05 to 60.

Hour and minute begin at perfect north position (as 00:00) then they run in clockwise direction like typical analog watch.
Specific hour and minute facets are backlighted to indicate current time.
Buttons for hour and minute adjustments are recessed onto the watch’s back access panel.

For visual differentiation, a thin polished metal threshold is designed to divide hour and minute facet groups.
For minimal interference to time indication backlights, jet crystal is used because it has lesser natural sparkles compare to other crystals.
For clear and coloured crystal variants, contrast coloured backlights are recommended.

Major intentions of Logical Sparkle are to re-rationalize crystal product and to simulate sparkles for further specific objectives.
It presents a new crystal function as crystal’s inherent property; by injecting a practical purpose (time indication) into its core material design stage (facet planning).
Further intention is to transform people’s perception of crystal product: - from an ornament to a smart daily device.
For jewellery lovers, Logical Sparkle’s unique time indication system provides an interesting topic plus further user experience.

Logical Sparkle is not a crystal ornamented watch. The crystal is the watch. The sparkle is the time.
