Bremont Supermarine 300MvsHamilton Jazzmaster Thinline Auto

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 Hamilton Jazzmaster Thinline Auto for its gorgeous, stunning, and captivating dials, particularly the champagne and burgundy variants, and its thin, comfortable profile, often noted at around 7mm to 8.4mm, making it ideal for wearability under shirt cuffs. The ETA 2892 movement is considered a strong value, though some owners report the rotor can be noisy and the winding feel unrefined, while others find the small crown difficult to manipulate. The absence of a second hand is polarizing, with some appreciating the simplicity and ease of setting, while others miss its presence. Overall, owners rate the Hamilton Jazzmaster Thinline Auto highly for its attractive, thin design and dial beauty at its price point.
