Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise Duckworth Prestex's customer service, with one owner receiving a replacement strap and a personal note. The Duckworth Prestex Broadgate GMT Automatic is available in five color options with rubber or metal bracelet choices, and is priced around $995. One owner finds the three different numeral fonts on the dial disorienting but appreciates the orange color as a great summer choice. On balance, owners value the brand's customer service and the watch's summer-ready aesthetic.
Owners widely praise the Zelos Spearfish GMT for its exceptional value and build quality, with one owner noting it garners more compliments than higher-end watches. Reviewers highlight its excellent machining, flawless finishing, and a superb bracelet featuring tool-less micro-adjustment that surpasses its price point. The watch is powered by a Sellita SW330-2 automatic movement. Some owners report accuracy around +2.6 seconds per day, while others note a minor compromise in end link fit. Overall, owners and reviewers rate the Zelos Spearfish GMT highly for its impressive finishing and bracelet at its $645 price.
The bezel action is a strong point. The bracelet quality is a weakness. Reviewers disagreed on the dial material, with some mentioning aventurine and others meteorite.
