What people say

Owners + reviewers, side by side

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

Hamilton Khaki Aviation Day Date Auto

Owners and reviewers widely praise the Hamilton Khaki Aviation Day Date Auto for its handsome, legible dial with raised indices and day/date complications, and its versatile, modern pilot watch design. The fully brushed case and good lume are noted strengths, with one owner finding it wears comfortably on a NATO strap. The H-10 caliber offers an 80-hour power reserve, though its decoration and regulation are less refined. Some find the 42mm size large and the skeletonized hour hand tip visually unappealing, while others note the AR coating is decent but not exceptional. Overall, owners and reviewers rate the Hamilton Khaki Aviation Day Date Auto highly for its practical design and value at its price point.

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.
