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.

Seiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition

The Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition is praised for its compact 40mm case and the new Caliber 6R55 movement offering a 72-hour power reserve. Owners and reviewers highlight the stunning dials as a strong suit for Seiko. However, the 6R movement's accuracy is a point of disappointment for some, who wish for improvements closer to other movements, though others accept it given the excellent overall package. Press images suggest the bracelet end links may appear disjointed. Overall, owners and reviewers rate the Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition well, with the stunning dials and improved power reserve being the biggest reasons.
