What people say

Owners + reviewers, side by side

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

Sternglas Naos Pro GMT Automatik

Owners report the Sternglas Naos can feel underwhelming with a cheap feel and hands resembling office printer output, with some finding it wears smaller than expected and looks like a toy, though others appreciate its understated design. Reviewers highlight the Argo Automatic variant as a compelling sub-€400 mechanical watch with a colorful dial and practical date wheel, suitable for new collectors, featuring a 38mm case and a Miyota 8215 movement. On balance, the consensus is that the Sternglas Naos offers a mixed ownership experience, with its value proposition and entry-level appeal being its strongest points for some.

From video reviewers

The Sternglas Naos Pro GMT Automatik features a clean Bauhaus design that sets it apart from other GMT watches. A notable weakness is the watch's bezel action, which is not as smooth as some reviewers would have liked. Reviewers disagree on the watch's case size, with one reviewer stating it's slightly larger than the original Naos Automatic, while another reviewer doesn't mention this aspect at all.

Tudor Black Bay 58 18K

Owners appreciate the substantial feel of the 18K gold Tudor Black Bay 58 on the wrist, with reviewers noting the brushed gold finishing and 39mm case size. The watch is powered by the COSC-certified Manufacture Caliber MT5400 with a 70-hour power reserve, visible through an open caseback. Sources offer differing price points, ranging from $16,800 to $32,100 depending on the strap or bracelet. Some reviewers criticize the brushed finish for diminishing the visual luxury of gold and find the green dial and bezel color combination divisive or lacking charisma. Overall, owners and reviewers find the Tudor Black Bay 58 18K to be an ambitious, albeit divisive, precious metal sports watch, with praise for its substantial feel and brushed gold finishing.
