What people say

Owners + reviewers, side by side

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

Oris Aquis Date Diamonds

Owners and reviewers widely praise the Oris Aquis Date Diamonds for its quality, value, and versatile design, with the glossy dial and ceramic bezel noted for playing with light, and the diamonds offering an interesting contrast. The comfortable integrated bracelet and rubber strap are frequently highlighted, as is the solid build and pleasing crown detail. Some owners find the 36mm size offers a substantial feel, while others note the 39.5mm variant's thickness and the amount of polished surfaces. Accuracy is reported as excellent, with one owner seeing +1 second per day. The Sellita SW 200-1 based Caliber 733 movement has a 38-hour power reserve. On balance, owners and reviewers rate the Oris Aquis Date Diamonds highly for its distinctive design and solid build quality at its price point.

Fortis Marinemaster M-40

Owners praise the Fortis Amber Orange for its gorgeous appearance and strong wrist presence, noting its crazy lume and 70-hour power reserve. The Doxa SUB 300T, described as having a superb, eccentric design with a highly legible dial and functional no-decompression bezel, uses an ETA 2824-2 movement. However, the SUB 300T's 42.5mm case wears large and its 14mm thickness is not ideal for dress shirts, though it boasts 1,200m water resistance. On balance, owners appreciate the Fortis Amber Orange for its striking aesthetics and impressive lume.
