Conventional mechanical watches can showcase the physical hour and minute hands as well as the structural beauty of the movement, but they have difficulty displaying notifications or digital information. In contrast, conventional smartwatches can provide a wide range of information, but their opaque displays have the limitation of covering the distinctive design elements of mechanical watches.

Vistar’s transparent Micro LED watch addresses these limitations. When the screen is turned off, it functions like a classic watch, with the hour and minute hands and gear structure clearly visible. When the screen is turned on, notifications and data are displayed on the transparent display. This allows users to retain the design appeal of a mechanical watch while simultaneously using smart functions.

The product features a TFT-based transparent Micro LED display measuring less than 2 inches. The Micro LED chip size is approximately 25 μm, and the non-emissive areas are designed to be transparent, enabling both high transmittance and high brightness. According to the company, the display supports 65% light transmittance and a peak brightness of more than 3,000 nits. It can display information even under strong ambient lighting, while at night, its transparency is emphasized, preserving the aesthetic appeal of a mechanical watch.

This product demonstrates that Micro LED technology can expand beyond large-format commercial displays into wearable devices and consumer products. It is particularly significant in that it delivers a differentiated design experience from conventional smartwatches through the use of a transparent display.
