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 HERITAGE CENTRAL POWER RESERVE

The Longines Conquest Heritage Central Power Reserve is widely praised for its beautiful, timeless, 1959-inspired dial and unique central power reserve indicator, with owners considering it a top dress watch in its price segment. Reviewers highlight its balanced layout and contemporary 38mm size, while some owners find the short lugs contribute to a comfortable wear. The watch features a modern 72-hour power reserve movement and is priced at $3,800. One reviewer notes the lugs are not curved enough, potentially creating a gap with the strap, though owners report the alligator strap softens with wear and some find the watch slightly chunky. A potential frustration for some owners is the power reserve indicator not always resetting to the same position when fully wound. On balance, owners and reviewers rate the Longines Conquest Heritage Central Power Reserve highly for its handsome vintage aesthetic and unique power reserve complication at an appropriate price.
