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 XL

Owners widely praise the Sternglas Naos XL for its versatile Bauhaus design, domed sapphire crystal, and value, with some finding its larger size comfortable and refined for its price. However, opinions are split on its aesthetic appeal, with one owner finding the hands and face underwhelming, while others appreciate the minimalistic dial. The date font is noted as too small to be useful by one owner, and the stock strap is generally considered basic or prone to wear. Accuracy figures vary, with one owner reporting a Miyota movement running fast and another noting +13 seconds per day. Overall, owners rate the Sternglas Naos XL highly for its Bauhaus aesthetics and affordability, despite some reservations about the movement and strap.

Zelos Spearfish GMT

The Zelos Spearfish GMT is widely praised for its exceptional value, with reviewers highlighting its superb finishing, flawless machining, and a tool-less micro-adjustment clasp that exceeds its price point. It features a La Joux-Perret G100 movement with a 68-hour power reserve, achieving an average accuracy of +2.6 seconds per day, or a Miyota 9075 movement offering flier-style GMT functionality. The 40mm case and bidirectional 48-click ceramic bezel are well-executed, though one reviewer noted a minor compromise in the end link fit. Overall, owners and reviewers rate the Zelos Spearfish GMT highly for its impressive finishing and value proposition.
