The Lemnos Muku Zelkova uses Japanese Zelkova that is specially sourced from the Japanese intra-trade market for wood specifically for the building of shrines and temples.  The UNESCO World Heritage Site the Kiyomizu-dera Temple of Kyoto built over 1200 years ago in the year 778, was made entirely with Japanese Zelkova. 
 
Muku is a desktop clock and does not have an alarm function.  It is made from a solid piece of wood - Japanese Zelkova.  Due to the important purpose of this particular wood, quality raw material of this wood specimen for making Lemnos Muku Zelkova Clocks is limited. 
 
The Muku is used by some of the world's high end hotels and resort as the guest room clock.
