What people say

Owners + reviewers, side by side

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

Grand Seiko SLGH017

Grand Seiko SLGH017 owners and reviewers widely praise its impeccable finishing on the applied markers and handset, and its lightweight titanium case and bracelet. The high-beat 9SA5 movement is noted for its approximately 80-hour power reserve, with accuracy figures reported by owners ranging from +4 sec/day to +5 to -3 seconds per day, though some owners express concerns about accuracy deviating significantly from specifications. Some find the "Night Birch" dial stunning and appreciate the Evo 9 case design, while others note the dial texture appears less pronounced on its matte black surface and criticize the handset's proportions and lack of lume. The Grand Seiko SLGH017 is priced at €10,500. On balance, owners and reviewers rate the Grand Seiko SLGH017 highly for its lightweight titanium construction and impeccable finishing.

Longines CONQUEST

Owners widely praise the Longines CONQUEST for its versatile, aesthetically pleasing design, comfortable wearability, and excellent value, with many highlighting its high-quality finishing and smooth winding action. Reviewers and owners alike note the watch's well-wearing size and blend of vintage and modern design elements. Some owners report the polished surfaces can be prone to scratches, and multiple sources flag the bracelet's lack of micro-adjustment as a significant drawback impacting fit. Lume quality is also a recurring point of criticism, with one reviewer noting only the black dial version appears to have lumed hands. Overall, owners and reviewers consider the Longines CONQUEST a highly versatile and well-built everyday sports watch offering significant value.

From video reviewers

The elegant gold dial is a notable aspect of the Longines CONQUEST. The quartz movement may be a drawback for collectors who prefer mechanical movements. Reviewers disagree on the standout feature, with one highlighting the gold dial and the other the Blue Sunburst dial.
