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

The Glycine Combat Sub is widely praised for its excellent value, thin case height (ranging from 10.4mm to 10.8mm), and comfortable wearability due to downward-curving lugs, with owners noting its quality and finishing punch well above its price point. Reviewers and owners consistently highlight its smooth bezel action, crisp font, and a unique aesthetic that avoids being a direct homage. However, criticisms include sub-par lume that is difficult to read in low light and an inconsistent power reserve, with some owners suggesting it may require servicing. Opinions are split on the 42mm size, with some finding it perfect and others preferring a smaller variant. On balance, owners and reviewers rate the Glycine Combat Sub highly for its exceptional thinness and quality finishing at its price point.

The Monta Atlas is widely praised for its exceptional wearability, with its comfortable 38.5mm case size and buttery bracelet frequently highlighted. Owners and reviewers alike commend its fit and finish, noting a mix of brushed, polished, and blasted surfaces. However, the rehaut on the opaline silver dial is considered nearly illegible for the 24-hour GMT scale, leading some to suggest other dial colors are more practical for GMT functionality. One owner also flagged the crown as less sturdy than anticipated and noted the AR coating attracts fingerprints. Overall, owners and reviewers rate the Monta Atlas highly for its comfortable dimensions and appealing finishing.

From video reviewers

The Monta Opalin Silver's dial is a notable strength, particularly its subtle gradient effect that adds depth to the watch without being too flashy. The watch offers a notable value proposition due to its movement, typically found in more expensive timepieces. The bracelet can be prone to rattle, which might be a trade-off for some buyers.
