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.

Formex Reef GMT

The Formex Reef GMT is widely praised for its unique porthole case shape, COSC-certified Sellita SW330-2 movement with good finishing, and comfortable quick-release bracelet with on-the-fly micro-adjustment. Reviewers note its robust construction, impressive specifications, and strong value proposition, with a slim 11.4mm profile accommodating 300m water resistance and an exhibition caseback. However, owners widely report the 53mm lug-to-lug span with male endlinks makes it too large for smaller wrists. Some find the bezel action stiff and potentially slippery, and a reviewer desired sharper finishing and edges, deeming the aesthetic too modernist. The GMT variant sacrifices a timing bezel unless swapped, and one owner notes sharp edges on the crown and crown guard. Overall, owners and reviewers highly rate the Formex Reef GMT for its exceptional value and well-executed features, particularly its bracelet system and COSC-certified movement.

From video reviewers

The watch features a COSC-certified SW330-2 GMT movement, which is visible through a sapphire crystal display case back and beautifully decorated. The watch's water-resistance of up to 300m/1000ft is a notable feature. The 42mm diameter may be too large for smaller wrists.
