Betula Borealis
The Northern birch, Betula borealis, is not only extremely rare but also subject to very strict regulation. It grows and thrives in the inhospitable cold area around the Yenisei, a 4.000-kilometre-long river in Siberia that flows to the Arctic coast and empties into the Kara Sea.

Northern Birch
Because the environment in which it grows is cold all year round, the Northern birch grows more slowly. Trees whose growth is suitable for making veneer are few and far between, and the Northern birch is therefore used for surface finishing only on very rare occasions.

Precision
The process employed to prevent distortion of the precious veneer and apply it to the front of the case is extremely complex. The bonding material used is an epoxide. A pigmentation-based method is used to fix the white colour permanently and to prevent it from yellowing under the influence of UV radiation.

Craftsmanship
As a final touch, the surface is sealed with 15 coats of high-gloss lacquer and polished by hand to a mirror finish. |
