What people say

Owners + reviewers, side by side

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

Echo/Neutra 1956 Chrono

Owners widely praise the Echo/Neutra 1956 Chrono for its gorgeous looks and clean design, with one owner calling it a top 5 watch in their collection. The 40mm size and included straps are noted as comfortable and wearable. Some owners find the watch difficult to read in dull lighting. One owner of a 1956 GMT reported a non-screwing crown, and another owner of a 1956 GMT noted a misaligned bezel. Overall, owners rate the Echo/Neutra 1956 Chrono highly for its aesthetic appeal and wearability.

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.
