The mechanical Grand Seiko Kodo Constant-Force Tourbillon SLGT003 watch is the Japanese brand’s first tourbillon not to be equipped with its ‘spring drive’ technology. The watch delivers constant power to the movement and boasts a tourbillon escapement to compensate for the effects of gravity. Several years in the making, it is the world’s first of its type to have the two complexities on a single axis as a single unit. It is crafted in platinum and Brilliant Hard Titanium.
