Batavi Watches Amsterdam AquamarinevsYema Skin Diver CMM.20

The Batavi Watches Amsterdam Aquamarine is praised for its original design and value, featuring a 39mm case with a hollowed mid-case and concave bezel. Reviewers note the Miyota 9039 movement offers standard accuracy of -10/+30 seconds per day. Some critiques mention the pull-out crown is short and overly polished, and the hollowed-out case flanks are a bit rough with a coarse finish. Overall, owners rate the Batavi Watches Amsterdam Aquamarine highly for its original design and value at the price.

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.
