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.

LONGINES SPIRIT FLYBACK PROTOTYPE

Owners widely praise the Longines Spirit Flyback Prototype for its attractive finishing, COSC-certified movement, and value as a flyback chronograph. Reviewers highlight its refined 39.5mm case and simplified dial, while some owners appreciate the reduced thickness and improved wearability compared to larger variants, with a lug-to-lug distance noted as potentially long for smaller wrists. The watch features a 68-hour power reserve and a bespoke L791.4 movement. However, the case thickness is a consistent point of discussion, with multiple sources citing 17mm, though some reviewers suggest thoughtful design makes it wear closer to 13.5-14mm. Owners are split on the dial's aesthetic, with some preferring previous configurations with gold subdial rings and concentric textures over the current flat matte dial and cut-off numbers. The leather strap is also noted as stiff and pinching.
