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.

Tudor Pelagos Ultra

The Tudor Pelagos Ultra is praised for its 1000 meters of water resistance, METAS-certified Calibre MT5612-U movement, and fully lumed dial and bezel. Reviewers highlight its titanium case and self-adjusting clasp as key features. The Tudor Pelagos Ultra is slightly larger at 43mm than some other models in the line but wears comfortably. Overall, owners and reviewers rate the Tudor Pelagos Ultra highly for its technical specifications and comfortable wearability as a flagship dive watch.

From video reviewers

The Tudor Pelagos Ultra's all-titanium construction provides a lightweight and durable case. One weakness is the lack of lume brightness. Reviewers disagree on whether the helium release valve is a notable feature or a drawback for a more streamlined design.
