What people say

Owners + reviewers, side by side

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

Glycine Combat Sub

Owners widely praise the Glycine Combat Sub for its exceptional thinness, with many noting its 10.4mm to 10.8mm profile for a diver, perfect proportions, and solid build quality that offers significant value, especially at discounted prices. Its unique aesthetic is appreciated for avoiding homage looks, and the lug design contributes to a smaller perceived wear size despite its 42mm case. Some owners report an inconsistent power reserve and sub-par lume that can be difficult to read at night, while one owner noted a slightly off-color lume pip on the chapter ring. Overall, owners rate the Glycine Combat Sub highly for its refined feel, slim profile, and value proposition.

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.
