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 Slim Auto

The Hamilton Jazzmaster Slim Auto is praised for its elegance, light weight, and impressive leather strap, offering a classy yet engaging aesthetic. Its thin 8mm profile, achieved partly by omitting a seconds hand and utilizing the ETA 2892 movement, contributes to its wearability. However, one owner notes the 44mm case size as being very large, and another finds it less appealing than vintage Hamilton models, though the black dial version is considered better looking. Overall, owners appreciate the Hamilton Jazzmaster Slim Auto for its slim profile and elegant design.

Studio Underd0g Full Moon

Owners widely praise the Studio Underd0g Full Moon's harmonious creamy dial and its 37mm case, which fits flawlessly. The innovative sapphire disc with numerals is a highlight, though two visible screws holding it are noted as a minor aesthetic drawback. Some owners find the watch overpriced, while others see value in the upgraded Sellita movement under $1k. Lume is surprisingly good, and the included NATO strap is preferred by some over the leather. Accuracy ranges from +1/+2 seconds per day to about -6 seconds per day. On balance, owners rate the Studio Underd0g Full Moon highly for its versatile dial and well-fitting case at the price point.
