What people say

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 GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
