What people say

Owners + reviewers, side by side

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

Boldr Expedition Enigmath

Boldr is widely praised for its attractive fumé dials, blend of sandblasted and polished case finishes, and excellent legibility. Owners report good build quality and value, with some calling it an excellent GADA or hiking watch, and the Miyota 9039 movement is noted for its smooth seconds hand sweep. However, the practical usefulness of the slide rule bezel is questioned, and some find the designs "microbrand-y" or potentially overpriced, with one owner reporting a negative warranty experience. On balance, owners and reviewers rate Boldr highly for its attractive dials and solid build quality at the price point.

From video reviewers

The watch's slide rule function is a convenient feature, allowing for calculations on the go. One potential drawback is the use of the Japanese Miyota 9039 movement, which may be a trade-off for some buyers. Reviewers disagree on whether the quick 'on the fly' adjust bracelet is a more significant advantage than the watch's sapphire crystal for durability and scratch resistance.

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.
