The founders of LIGURE WATCHES wanted to include a GMT in their collection as a special and in a limited edition of 100 pieces with "Founders Edition" on the dial. GMT stands for 'Greenwich Mean Time'. What sets this Tartaruga apart from the other, is its ability to display two different timezones at once. It features an extra red hour hand coaxially located at the center of the dial that uses a 24 hour scale.
