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.

Spinnaker Dumas Automatic

Owners widely praise the Spinnaker Dumas Automatic for its attractive textured blue dial, applied indices, and well-finished case, noting its comfortable wearability due to a short lug-to-lug distance. Some owners flag the use of mineral crystal instead of sapphire and a bracelet with a learning curve and loose keeper. Overall, owners rate the Spinnaker Dumas Automatic highly for its aesthetics and case finishing at its price point.
