What people say

Owners + reviewers, side by side

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

Citizen Promaster Sikorsky

The Citizen Promaster Sikorsky is a large 46mm watch honoring the S-92 helicopter, featuring a busy dial with red, white, blue, and yellow accents, and helicopter blade-shaped hands. It houses a solar-powered U680 movement with atomic time syncing. On balance, owners find the Citizen Promaster Sikorsky to be a unique, albeit cluttered, limited edition timepiece.

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.
