The maker
Monomods
Monomods positions itself against "watch hype" — pushing back on watches that look premium but hide what actually matters: overdesigned dials, inflated stories, and no clarity about what's inside or who stands behind it. Their stated response is transparency: using proven Japanese movements, transparent components, and careful assembly, with real support after purchase
