Batteries not needed.
Mechanical movements, with their high level of craftsmanship and precision engineering, cost far more than quartz movements and are preferred for use in higher-end timepieces.
Unlike the standard, no-frills quartz watches that run on batteries, mechanical timepieces are powered by energy stored and harnessed through an intricate clockwork of tiny gears and springs, a technology that preceded quartz watches by almost a thousand years.
At Gruppo Gamma we've curated a spectrum of self-winding (automatic) and hand-wound mechanical movements. These movements have been chosen for their class-leading reliability, robustness and smooth second hand sweep that's seen in fine timepieces. They're easy to maintain and should run trouble-free for many years.
