What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

BOLDR x Nitecore

BOLDR x Nitecore is widely praised for its lightweight 38mm PVD titanium case, excellent legibility, and perfect sizing. Owners and reviewers highlight the unique, topographical map-inspired dial offering fantastic depth, complemented by color-matched Old-Radium C3 lume and subtle branding. 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.

Citizen Promaster Sikorsky

The Citizen Promaster Sikorsky is a large 46mm watch honoring the S-92 helicopter, featuring a busy dial with red, white, blue, and yellow accents, and helicopter blade-shaped hands. It houses a solar-powered U680 movement with atomic time syncing. On balance, owners find the Citizen Promaster Sikorsky to be a unique, albeit cluttered, limited edition timepiece.
