What people say

Owners + reviewers, side by side

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

Hamilton Khaki Aviation Takeoff Auto Chrono

The Hamilton Khaki Aviation Takeoff Auto Chrono is noted for its unique bullhead chronograph design and detachable functionality for desktop display, with a PVD case and yellow accents. Owners praise its solid construction, precise indices, and smooth bezel action, alongside a detailed champagne dial, crisp printing, and retro hands with good lume. However, its extreme thickness and 46.3mm width are flagged as compromising daily wearability, and some find the sizable crown guards hinder usability, while a rattling bracelet with a difficult-to-remove design is also mentioned. The watch uses the Hamilton H-31 automatic chronograph movement with a 60-hour power reserve and is a limited edition of 1999 units. On balance, owners and reviewers appreciate the Hamilton Khaki Aviation Takeoff Auto Chrono for its distinctive design and pilot-inspired legibility, despite practical concerns regarding its size and wearability.

Phoibos Wave Master GMT

The Phoibos Wave Master GMT is widely praised for its attractive design, comfortable 20mm tapering bracelet, and wearability on a 7" wrist, with owners finding it a strong value proposition at $220. Some minor finishing flaws, such as slightly crooked markers and off-center dial numbers, are noted by one owner, while accuracy averages around 5-10 seconds over two weeks. Overall, owners rate the Phoibos Wave Master GMT highly for its distinctive design and comfortable wearability at its price point.

From video reviewers

The Wave Master GMT's notable feature is its 200M water resistance. A drawback is the rattle of the bracelet. Reviewers disagree on the watch's value, with one reviewer noting its significant weight for a 39.5mm case diameter, but the other reviewer doesn't mention any specific weaknesses or trade-offs.
