What people say

Owners + reviewers, side by side

The watch is described as durable and powerfully lumed, with the included Nitecore TIKI torch capable of boosting its glow. On balance, owners and reviewers rate the BOLDR x Nitecore highly for its exceptional lume and distinctive dial design at its price point.
