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.

Baltic Prismic

The Baltic Prismic is widely praised for its unique stone dials, slim 9.2mm case, and retro-chic design, with reviewers highlighting its impressive build quality and detailed finishing for the price. Owners appreciate the complex five-part case construction using steel and titanium, and the attractive dial textures. The hand-wound ETA Peseux 7001 movement is consistently mentioned, offering a 42-hour power reserve. However, some owners find the watch overpriced and the bracelet unappealing or flaring on smaller wrists, while the 30-meter water resistance is noted as delicate. The avant-garde dial design is also described as divisive by one reviewer. Overall, owners and reviewers rate the Baltic Prismic highly for its distinctive stone dials and slim, vintage-inspired case at an accessible price point.

From video reviewers

The Baltic Prismic's unique natural stone dials, each using a slice of thousand-year-old stone, are a standout feature. A notable drawback is the price, with several reviewers mentioning it as a potential issue, particularly considering the finishing and uniqueness offered. Reviewers disagree on the watch's ruggedness, with some viewing it as a dress watch and others not mentioning this aspect.
