About the Brand:

The collection of watches by Frankstone®, The Wellness Watch® all boast a distinctive, exclusive new feature: transparency.

All the watches in the collection have been designed with a particular transparent window in the face that reveals the stone positioned at the back of the watch case. In the men's models Nahual and Daemon the stone can be seen through a circular window cut out into the left side of the watch face. In the women's models Duality and Duality Glam, the whole of the back of the watch case is in transparent glass.
 
Transparency has always been a symbol of freedom and wellbeing, able to provide comfort and conjure up a special atmosphere. Transparency is also the element best able to convey the idea of feeling free to be just what we want to be.
