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 Seastar 1000 Chronograph

Owners widely praise the Tissot Seastar 1000 Chronograph for its captivating blue dial, excellent case finishing, and legible matte dial, with some noting its Powermatic 80 movement offers remarkable accuracy averaging -0.6 seconds per day and an 80-hour power reserve. The ceramic bezel is also frequently highlighted as exceptionally well-done, and the bracelet is described as surprisingly strong. However, multiple owners report issues including bezel looseness, paint chipping, flooding, a broken crown, and a protruding case back causing discomfort. Some find the watch too large, with one owner noting unfinished case sides and a crown pattern that digs into fingers. Overall, owners rate the Tissot Seastar 1000 Chronograph highly for its impressive finishing and value, despite a notable number of reports concerning durability and comfort issues.
