The Vostok-Europe Systema Periodicum Boron Mecha-Quartz Chronograph Watch VK67-650E721 is a testament to meticulous craftsmanship and ingenious design, proudly handmade in Lithuania. This watch is an integral part of the Systema Periodicum collection, which derives its creative essence from the Periodic Table of Chemical Elements, commonly known in Latin as “Systema Periodicum.” Introduced in 1869, this significant scientific framework organizes the 118 known elements and provides insights into the characteristics of yet-to-be-discovered elements, marking a monumental achievement in the realms of chemistry, physics, and other scientific disciplines.

This model pays tribute to Boron (B), a substance characterized by its pure black crystals when in solid form. Boron is commonly found in nature combined with oxygen and other elements, forming various borates compounds.
