Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Hamilton Jazzmaster Thinline Small Second Quartz for its excellent value around $300, thin profile at 7mm to 8.4mm, and clean dial design with superb applied hour numerals and dauphine hands. One owner finds its champagne dial particularly upscale. However, the lume is considered terrible, barely lasting a few minutes, and the crown is noted as very small and difficult to manipulate. On balance, owners rate the Hamilton Jazzmaster Thinline Small Second Quartz highly for its thinness and clean dial design at the price.
Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
