What people say

Owners + reviewers, side by side

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

Glycine Combat Sub Sport

Owners widely praise the Glycine Combat Sub Sport for its exceptional thinness, with multiple sources noting profiles between 10.4mm and 11mm, comfortable wearability on a variety of wrist sizes due to its proportions and contoured lugs, and its value, especially when found under $400. Some owners highlight its refined finishing and unique, non-homage design, while others appreciate its ruggedness and durability, with one noting PVD coating remained flawless after three years of heavy use. Accuracy figures range from excellent, with one owner reporting only 2 seconds lost per day, to inconsistent power reserve and occasional reported issues with the movement and stem. The lume is described as subpar by some, though one owner found it marginally better than a Seiko SKX007. Reservations are occasionally raised regarding warranty service and the use of folded end links on the bracelet.

Oak & Oscar The Olmsted 38

Oak & Oscar The Olmsted 38 is praised for its sharp, stealthy aesthetic with a durable ceramic-coated stainless steel case and a clean, no-date dial. Reviewers highlight its excellent wearability at 38mm and the value proposition at $1,475, which includes two strap options. The watch features a sandwich dial with stencil numerals and orange accents, powered by a modified ETA 2892-A2 movement. Overall, reviewers find Oak & Oscar The Olmsted 38 to be a modern and aggressive take on the classic field watch, offering exceptional value.
