What people say

Owners + reviewers, side by side

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

Bell & Ross BR-05 GMT Sky Blue

Owners and reviewers widely praise the Bell & Ross BR-05 GMT Sky Blue for its excellent finishing, sharp transitions between brushed and polished surfaces, and attractive blue sunray dial. It is noted to wear well on wrists under 6.5 inches. Some owners question its value proposition due to the Sellita movement, and one owner finds the crown can be fussy to use, while another notes sharp edges on the bracelet links. Overall, owners and reviewers rate the Bell & Ross BR-05 GMT Sky Blue highly for its cohesive package and attractive case execution.

Hamilton Jazzmaster Maestro Auto Chrono

Owners widely praise the Hamilton Jazzmaster Maestro Auto Chrono for its dramatic increase in quality and attention to detail, its versatile dial layout suitable for dressing up or down, and its bulletproof build that remains problem-free for years. Accuracy figures range from gaining about 5 seconds per day to keeping time within 10 seconds per day even after extended periods without service. Some owners find the lack of a second hand a deal-breaker, and the 45mm size can be chunky and may not fit under shirt sleeves. Concerns exist regarding the movement's serviceability, high maintenance costs, and intervals. On balance, owners rate the Hamilton Jazzmaster Maestro Auto Chrono highly for its robust build and quality for the price, despite some reservations about its size and serviceability.
