Reviews

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

Circula Watches AquaSport GMT

Owners widely praise the Circula Watches Taucheruhren von CiRCULA for its exceptional quality and value for the price, with many citing its robust construction, including hardened stainless steel and strong anti-magnetic technology. Some owners find the watch comfortable and well-suited for smaller wrists, appreciating the clean dial and the inclusion of bonus accessories like extra straps and tools. One owner noted the Sellita SW330-2 movement as a strong point at this price. However, one owner found the lug-to-lug length too long and the watch too heavy for all-day wear, preferring a different size. Overall, owners rate the Circula Watches Taucheruhren von CiRCULA highly for its impressive build quality and value proposition.

Yema Skin Diver CMM.20

The Yema Skin Diver CMM.20 is lauded for its vintage aesthetic, 39.5mm case size, and well-proportioned handset with sharp indices. Owners praise its textured cream dial, French tool watch elegance, and the smooth winding feel of the in-house CMM.20 micro-rotor movement. The fully brushed bracelet with toolless micro-adjust clasp is considered Yema's best yet. Accuracy readings range from -3/+7 seconds per day to approximately 0 to -10 seconds per day. Some reviewers noted questionable finishing on a prototype's hour hand and a rattly, stamped clasp. The watch's pricing has been questioned by some due to brand QC reputation, and its extended lug-to-lug may challenge smaller wrists. On balance, owners and reviewers appreciate the Yema Skin Diver CMM.20 for its vintage styling and improved bracelet design at its price point.

From video reviewers

The sapphire bezel insert and in-house CMM.20 movement are noted strengths. Reviewers questioned the value proposition compared to other Yema models.
