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.

Longines MASTER COLLECTION

Owners and reviewers widely praise the Longines Master Collection for its excellent fit and finish, heritage-inspired design with features like Breguet numerals and leaf hands, and the value it offers, particularly for complications like chronographs and annual calendars. Specific models are noted for their beautiful dial execution, creamy white barleycorn or blue starburst finishes, and practical complications. Some owners find the Master Collection thin and dressy, appreciating its vintage aesthetic. However, drawbacks mentioned include a subdial potentially obscuring numerals, a bracelet lacking micro-adjustments causing fit issues for some, and a case finishing described as homogenous by one owner. The 30m water resistance on annual calendar models is considered light, and the crown and pushers on the moon phase chronograph are described as uninspiring. One owner reported a broken moon phase setting mechanism.

From video reviewers

The diamond hour markers are a notable strength. The movement accuracy was not discussed.
