What people say

Owners + reviewers, side by side

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

Vario 1918 Trench Brass

Owners widely praise the Vario 1918 Trench Brass for its attractive, precisely made dial and case, with the evolving brass patina noted as a positive feature. The bund strap is considered comfortable and well-fitting by some, though others find it stiff and short for larger wrists. The lume is considered poor. The Miyota 82s5 movement is described as adequate, with accuracy ranging from about -10 seconds per day to simply running slow. On balance, owners rate the Vario 1918 Trench Brass highly for its fantastic looks and the unique character of its brass case.

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.
