Tertium Quid Watch Tokyo: For experienced, by experienced

Concept of "Tertium Quid Watch"

Tertium Quid is a Latin phrase meaning 'a third something' or 'a third substance that is distinct from two others.' Our mission is to create the 'Tertium Quid'—a third distinct entity—for the experienced collector. You possess deep appreciation for dress, sport, casual, and tool watches, yet we recognized a space beyond these established categories. We forge an entirely new class of timepiece that synthesizes the best aspects of traditional genres while transcending their limitations, delivering a unique instrument specifically for those who thought they had seen it all.
