What people say

Owners + reviewers, side by side

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

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.

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.
