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.

YEMA x Silberstein Marine 2 CMM.20 Limited Edition

The YEMA x Silberstein Marine 2 CMM.20 Limited Edition is noted for its slim 39mm case and in-house CMM.20 micro-rotor movement, offering 300 meters of water resistance and a 70-hour power reserve. Reviewers highlight the watch's thin profile and flowing case design, as well as its black lacquered enamel dial. However, the bezel's lack of numbers is considered a practical drawback, and one reviewer noted the audible spin of the micro-rotor, which was unexpected given the €1,990 price for the 200-piece limited edition. The included leather strap is also seen as less suited for the watch's dive capabilities. Overall, reviewers appreciate the YEMA x Silberstein Marine 2 CMM.20 Limited Edition for its slim design and in-house movement, though practical considerations regarding the bezel and strap are noted.
