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 SPEEDTIMER Seiko 145th Anniversary Limited Edition

Owners widely praise the Prospex SPEEDTIMER Seiko 145th Anniversary Limited Edition for its refined presence and intricate dial patterns, with some favoring its unique red dial and steel bezel over other Speedtimer models. However, some owners criticize the 24-hour subdial as useless, the date window as recessed, and the stock bracelet as difficult to fit, while others find the pushers stick out too much. One owner notes the $995 price point is high for the 6R55 movement, suggesting a lower range, though others appreciate the Seiko finishing and charm. On balance, owners rate the Prospex SPEEDTIMER Seiko 145th Anniversary Limited Edition well for its unique aesthetic and finishing, despite some functional and value concerns.
