Grand Seiko SLGW003

The Grand Seiko SLGW003 is praised for its comfortable, lightweight Brilliant Hard Titanium case, meticulous finishing, and a clean, modern dial. Reviewers highlight the new 9SA4 manual-wind movement, noting its attractive finishing, 80-hour power reserve, and accuracy of -3/+5 seconds per day. It is considered a versatile dress watch blending vintage and future Grand Seiko spirit. The €11,700 price is noted as expensive, with some questioning its value. Overall, reviewers rate the Grand Seiko SLGW003 highly for its elegant design and impressive manual-wind movement at its flagship price point.

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.
