What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Baltic Aquascaphe Dual-Crown - Black PVD

The Baltic Aquascaphe Dual-Crown - Black PVD is widely praised for its refined case finishing, including polished chamfers and brushed lugs, and its comfortable, wearable 39mm size. Reviewers highlight its clean dial design and excellent legibility, with some noting improved legibility from larger lume-filled markers. The functional internal bezel, operated by a non-screw-down crown, is a key feature for dive timing. The watch utilizes a Miyota 9039 automatic movement with a 42-hour power reserve and hacking seconds. One reviewer found the 4 o'clock crown for time setting to be fiddly, and another noted the sapphire crystal can be somewhat reflective. The price is cited as €550 or €650 (ex VAT). On balance, reviewers commend the Baltic Aquascaphe Dual-Crown - Black PVD for its vintage-inspired aesthetic combined with modern build quality and wearability at its price point.

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.
