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 Heritage 1973

The Tissot Heritage 1973 is widely praised for its faithful vintage aesthetic, featuring a tonneau or cushion case with contrasting finishes and a panda dial with orange accents. Owners and reviewers alike appreciate its compelling remake of a 1970s racing watch, with some specifically noting the attractive dial and case curves. The watch is powered by the ETA 7753 automatic chronograph movement, offering a 60-hour power reserve. However, some find its 43mm or 44mm diameter to be large-wearing, and one owner reported difficulty setting the date and a chronograph reset that is consistently one second off. Accuracy figures vary, with one owner noting 10-15 seconds per day. The radial brushed case finish, while visually appealing, is noted as being prone to scratches that are difficult to polish out. Overall, owners and reviewers rate the Tissot Heritage 1973 highly for its tempting value and credible vintage racing style.
