What people say

Owners + reviewers, side by side

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

Baltic Hermétique Summer

Reviewers highlight the Baltic Hermétique Summer's compact 37mm brushed case with a polished bezel and 150 meters of water resistance. The watch features glossy dials in bright colors with raised BGW9 Super-LumiNova indices that emit a strong blue glow, and it comes with color-matched FKM rubber straps or Baltic bracelets. The Miyota 9039 movement supports hacking and hand-winding. However, the recessed crown can be difficult to manipulate if fingernails are not long enough, and the movement has a stated accuracy of -10/+30 seconds per day. Overall, reviewers praise the Baltic Hermétique Summer for its well-balanced, colorful dials and strong lume at an affordable price point.

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.
