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.

Geckota Pioneer Automatic

Owners widely praise the Geckota Pioneer Automatic for its retro-futuristic design, impressive lume, and unique dial finishing. The red dial variants are particularly favored for their brushed fumee appearance and vintage feel. Accuracy is noted as surprisingly good for an NH35 movement, though one owner reports +/- 20 seconds per day. The watch is considered a bargain by some at $259, while others find the $519 price for the NH35 movement in a 14mm thick case excessive. The 42mm cushion case is noted to wear large due to its lack of a prominent bezel. A minor phantom date position on the crown is reported, and the crystal is very reflective despite an anti-reflective coating. Some find the gold accents look a bit cheap, and one instance of a loose fleck of lume was observed. Overall, owners rate the Geckota Pioneer Automatic highly for its distinctive vintage aesthetic and value, particularly on sale.
