Reviews

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

Hamilton Khaki Navy Scuba Auto

Owners widely praise the Hamilton Khaki Navy Scuba Auto as an excellent value proposition under $1,000, highlighting its distinctive design, legible lume, and tactile bezel. Some owners appreciate its 40mm case size for comfortable everyday wear, while others find the 43mm variants feel great on the wrist. The H-10 automatic movement provides an 80-hour power reserve. However, the 43mm case size is noted as large by some, and the steel bracelet could benefit from a taper and a quick-adjust clasp. On balance, owners and reviewers rate the Hamilton Khaki Navy Scuba Auto highly for its robust tool watch design and impressive value at its price point.

From video reviewers

The 80-hour power reserve from the H-10 movement is a significant strength. Reviewers noted the bezel action and bracelet/clasp as points of focus.

Thorn Titanium 39mm Automatic Dive Watch

Owners widely praise the Thorn Titanium 39mm Automatic Dive Watch for its exceptional lightness and comfort due to its titanium construction, with many highlighting the impressive finishing and the "game-changer" tool-free bracelet adjustment system. The lume is also frequently called out as superior. However, some owners find the watch wears a little small, and one owner returned it due to a ghost-date issue and the watch stopping once every 24 hours, with another reporting the watch stopped when the seconds hand reached 60. The design is described by one owner as somewhat uninspired, aside from the custom dial, due to common mod parts. Overall, owners rate the Thorn Titanium 39mm Automatic Dive Watch highly for its wearability and bracelet system.
