Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
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.
Owners widely praise the Grand Seiko SBGR299 for its striking blue second hand, silver rhodium dial, no-date design, and the impressive 72-hour power reserve, noting its excellent value. The watch's high polish finishing is frequently described as outstanding, akin to a polished samurai sword. Some owners express concern over legibility due to silver hands on a silver dial, though this is not a universal sentiment. One owner reported accuracy of approximately -20 seconds per day, while another found the 42mm case size wearable. The pre-owned price is noted around $3,399.00. Overall, owners rate the Grand Seiko SBGR299 highly for its exceptional finishing and distinctive design elements at its price point.
