What people say

Owners + reviewers, side by side

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

Boldr Expedition Enigmath

The watch's slide rule function is a convenient feature, allowing for calculations on the go. One potential drawback is the use of the Japanese Miyota 9039 movement, which may be a trade-off for some buyers. Reviewers disagree on whether the quick 'on the fly' adjust bracelet is a more significant advantage than the watch's sapphire crystal for durability and scratch resistance.

Wolbrook Skindiver Automatic

The Wolbrook Skindiver Automatic is widely praised for its attractive vintage aesthetic, comfortable wearability, and legible dial, with many owners highlighting its quality build and value under $500. Owners often commend the Beads of Rice bracelet and tropic strap, the box sapphire crystal, and the overall solid feel that suggests nothing is cheap. Specific praise is given to its lume, which some find lasts well and is great, and its accuracy, with one owner noting exceptional performance. However, some find the finishing merely fine, not exceptional, and note issues with the push-pull crown lacking a positive lock or being noisy. The 20mm strap width and drilled lugs that don't fit all spring bars are also mentioned as potential drawbacks. The Miyota 8315 movement, while preferred over the 8215, is described by one owner as noisy, and the non-transferable warranty policy is a concern for some.
