What people say

Owners + reviewers, side by side

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

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.

Zelos Spearfish Dual Time

Owners widely praise the Zelos Spearfish Dual Time for its attractive design and the well-executed big date complication. The watch is described as a non-attention-seeking option that looks awesome, with a thickness of 12mm including the crystal and 10mm without. One owner found the $1900 price tag too expensive and uncharacteristic for the brand. On balance, owners rate the Zelos Spearfish Dual Time highly for its attractive design and the well-executed big date complication.
