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.

Tornek-Rayville Blakjak 12-hr GMT

The Tornek-Rayville Blakjak 12-hr GMT is a 42.5mm stainless steel watch featuring a DLC-coated bezel, sapphire crystal, and a matte black dial with 12- and 24-hour scales. It is powered by a Seiko SII NH36 automatic movement, offering a 41-hour power reserve, and boasts 200 meters of water resistance. The dial includes a day/date complication and Super-LumiNova BGW9 lume. Overall, owners and reviewers highlight its robust build and functional military-inspired design as key strengths.
