What people say

Owners + reviewers, side by side

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

CWC T20 General Service Quartz Watch

The CWC T20 General Service Quartz Watch is widely praised for its simple, clean, and classic look, with owners considering it a classy and comfortable field watch. Its 38mm tonneau case is seen by some as a cool retro piece representative of original MOD specifications, though others find this size too small for larger wrists. The watch is noted for keeping accurate time, with one owner reporting it as practical for everyday wear. It features a stainless steel case, sapphire crystal, and a Ronda 715 movement. A limitation mentioned is the fixed lugs, which restrict strap versatility. Overall, owners rate the CWC T20 General Service Quartz Watch highly for its classic military-inspired aesthetic and reliable timekeeping at an affordable price.

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.
