Reviews

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

Duckworth Prestex Broadgate GMT Automatic

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.

Grand Seiko SBGM245

Owners widely praise the Grand Seiko SBGM245 as a compelling mechanical GMT, blending sport and luxury with notable workmanship. Some owners find its 40.5mm case size and 14.4mm thickness wearable, while others consider it too large and prefer slimmer alternatives. The polished surfaces are noted to scratch easily, suggesting it is best suited for dressier occasions. Accuracy figures vary, with one owner reporting an average gain of two seconds per day, while others express a desire for a thinner case and a clasp with quick extension. Overall, owners rate the Grand Seiko SBGM245 highly for its mechanical GMT functionality and craftsmanship, despite some reservations about its size and scratch resistance.
