Pierre image : RockWatch en "jaspe paysage"

Montre RockWatch R151 en Jaspe avec dendrite (désert du Kalahari), produite par la manufacture horlogère TISSOT dans les années 80.

The granite used to make the Tissot RockWatch cases came from the Alps in the Grischun, Ticino, and Valais areas.
Later versions of the Tissot RockWatch used different stones from various mountainous regions around the world, including alabaster, Brazilian aventurine, and blue sodalite, Scandinavian basalt, blue lace agate, Italian lapis lazuli, magnesite, picture jasper from Kalahari desert, Australian pink rhodonite, quartz, and thulite.
Some pieces received decorative dial inserts such as sectors from prehistoric clamophyllia coral as a premium option.
