This collection was born in symbolic support for the ‘Go Red for Women’ movement, standing against heart disease in women, each of the timepieces feature a tiny red heart at 3 o’clock. Tressia is also a line of watches incorporating advanced technology such as the SEIKO Solar, with all types of light that enter the case being transformed into energy. Three bar water resistance, a 12 month power reserve and the fact the battery never has to be changed make the watches in this collection truly sustainable.
