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.

Tissot PRX

The Tissot PRX is widely praised for its exceptional finishing, comfortable wearability, and strong value proposition, with owners and reviewers highlighting its luxurious feel for the price. The integrated bracelet, often noted for its shine, finishing, and brushed surfaces with polished edges, is a significant draw, as is the watch's neo-vintage aesthetic and refined dial pattern. The slim case profile, measuring around 10.5mm to 11mm depending on the source, contributes to its comfortable daily wear, and the 100m water resistance is a practical feature. While one owner reported specific issues with a PRX Chronograph's hands and quality control after service, other sources focus on the Powermatic 80's reliable automatic movement and the overall joy of wearing the Tissot PRX. Some find sizing the bracelet challenging due to the lack of a micro-adjustment option.

From video reviewers

The Powermatic 80 movement with its 80-hour power reserve is consistently praised. The lume brightness is noted as a weakness. Reviewers disagree on the suitability of the lug-to-lug fit for smaller wrists.
