What people say

Owners + reviewers, side by side

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

Hamilton Jazzmaster Skeleton Auto

The Hamilton Jazzmaster Skeleton Auto is praised for its redesigned dial that balances complexity and legibility, forming an "H" logo and highlighting the H-10-S movement. Owners appreciate the 80-hour power reserve and the seamless blend of the bracelet with the lugs. The watch is available in 40mm and 36mm sizes, with prices ranging from A$1,925 to A$2,200, and features 50m water resistance. Overall, owners and reviewers rate the Hamilton Jazzmaster Skeleton Auto highly for its distinctive dial design and impressive power reserve at its price point.

From video reviewers

The 80-hour power reserve from the H-10 automatic movement is a notable strength. Water resistance to 5 ATM is considered on the lower side for the price point.

Gruppo Gamma Field III GMT Date

Owners widely praise the Gruppo Gamma Field III GMT Date for its awesome looks, quality, and good value. The watch features a 40mm brushed 316L stainless steel case, box sapphire crystal, and 200m water resistance, powered by a Seiko NH34A movement. Some reviewers note the NH34A movement's accuracy can range from -20~+40 seconds per day, though one reviewer reported +5 seconds per day with a regulated movement. The dial's dense layout with Arabic numerals can be overwhelming for some, and one owner found the size unsuitable for smaller wrists. On balance, owners rate the Gruppo Gamma Field III GMT Date highly for its impressive finishing and toolish design at its price point.
