What people say

Owners + reviewers, side by side

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

Islander Black DLC Aviator Automatic Watch with Leather Strap and an Anti-Reflective Sapphire Crystal #ISL-46

Owners widely praise the Islander Black DLC Aviator Automatic Watch with Leather Strap and an Anti-Reflective Sapphire Crystal #ISL-46 for its anti-reflective sapphire crystal, legible dial, and strong C3 lume. The Seiko NH35 movement, featuring hacking and hand-winding, is also a commonly cited positive, contributing to its value at a $199 sale price. Some owners appreciate the clean, unbranded dial, aligning with traditional Flieger design. However, one owner notes the watch runs fast, requiring frequent time adjustments, and another commenter feels the date complication detracts from the Flieger aesthetic. Overall, owners rate the Islander Black DLC Aviator Automatic Watch with Leather Strap and an Anti-Reflective Sapphire Crystal #ISL-46 highly for its value and classic Flieger design elements.

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.
