What people say

Owners + reviewers, side by side

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

Bremont Supermarine 300M

The Bremont Supermarine 300M is praised for its comfortable 40mm and 42mm case sizes, with owners noting the 42mm wears well on smaller wrists due to its lug design. One owner highlights the 13mm thinness of the 40mm case, considered compact for a 300m diver. The watch is priced at $1375. On balance, owners and reviewers appreciate the Bremont Supermarine 300M for its wearability and compact dimensions, especially for a dive watch.

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.
