What people say

Owners + reviewers, side by side

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

Raven Trekker

Owners widely praise the Raven Trekker for its classic yet unique design, excellent bracelet, killer BGW9 lume, and overall value, with many finding the 39mm case size perfect and appreciating its blend of explorer and dive watch aesthetics. Reviewers and owners consistently flag the tight, play-free bezel action and the crisp, legible dial. Some owners note the Miyota 9015 movement's rotor can exhibit wobble, the crown threads can feel grindy, and the bracelet's solid end links can be difficult to reinsert, with one owner finding the 2022 bracelet too simple. Overall, owners rate the Raven Trekker highly for its exceptional value and tool-watch build at the price point.

Gruppo Gamma Field III GMT

Owners praise the Gruppo Gamma Field III GMT for its look and value, with specific mentions of its sandwich dial and comfortable OEM straps. One owner notes incredible quality for the price across their Gruppo Gamma watches. The watch features a 40mm brushed stainless steel case, box sapphire crystal, and a Seiko NH34A movement with a 41-hour power reserve and stated accuracy of -20~+40 s/day. Some find the lack of a date window a drawback for a GMT, and question its differentiation from other NH34-powered watches. On balance, owners and reviewers find the Gruppo Gamma Field III GMT to be a good value with quality construction for its price point.
