What people say

Owners + reviewers, side by side

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

Monta Atlas

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.

Seiko 5 Sports SKX series

The Seiko 5 Sports SKX series is widely praised for its value, robust build, and powerful lume, with owners appreciating its comfortable bracelets and improved movement featuring hacking and hand-winding. Some owners find the original SKX models heavy and bulky, while others praise their ruggedness and iconic dive watch design. Reviewers note the 38mm models offer great value at around €350 and are exemplary gateway watches, though their 100m water resistance without a screw-down crown makes them unsuitable for diving. The Seiko 5 Sports SKX series is seen as a decent watch, especially under £200, but lacks the tool watch capabilities of the original SKX, missing a screw-down crown, bezel pip, and ISO rating. On balance, owners and reviewers rate the Seiko 5 Sports SKX series well for its blend of value, improved movement, and tool-watch aesthetic, despite some missing dive certifications.
