What people say

Owners + reviewers, side by side

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

AVI-8 Hawker Hunter Retrograde Chronograph

Owners widely praise the AVI-8 Hawker Hunter Retrograde Chronograph's airplane-inspired dial design and the comfortable, soft leather strap with a no-break-in clasp. However, one owner notes that the case, crown, and glass crystal fitment left much to be desired, feeling cheap, and the mineral glass is prone to scratching. The watch is considered overpriced for its features, though appealing when found on sale. On balance, owners find the AVI-8 Hawker Hunter Retrograde Chronograph appealing for its unique dial and comfortable strap, despite concerns about case finishing and the mineral crystal.

Sinn U50 HYDRO SDR with TEGIMENT option

The Sinn U50 HYDRO SDR with TEGIMENT option is widely praised for its exceptional scratch resistance and legibility, with owners reporting no signs of wear after extended use. The oil-filled case contributes to extreme water resistance and a clear dial, while the fully tegimented construction offers a soft feel on the wrist. Reviewers note the compact 41mm size, though one owner found it did not wear as thin as expected due to its thickness. The lume is considered underwhelming by some, and the diving extension on the clasp can release too easily. It utilizes a quartz movement, which is noted as less accurate than previous thermo-compensated options. Overall, owners and reviewers rate the Sinn U50 HYDRO SDR with TEGIMENT option highly for its robust, legible, and virtually indestructible build at its price point.
