What people say

Owners + reviewers, side by side

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

Hamilton Jazzmaster Thinline Small Second Quartz

Owners widely praise the Hamilton Jazzmaster Thinline Small Second Quartz for its excellent value around $300, thin profile at 7mm to 8.4mm, and clean dial design with superb applied hour numerals and dauphine hands. One owner finds its champagne dial particularly upscale. However, the lume is considered terrible, barely lasting a few minutes, and the crown is noted as very small and difficult to manipulate. On balance, owners rate the Hamilton Jazzmaster Thinline Small Second Quartz highly for its thinness and clean dial design at the price.

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.
