What people say

Owners + reviewers, side by side

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

Massena LAB Dato-Racer

Owners widely praise the Massena LAB Dato-Racer as an excellent everyday watch, appreciating its blend of 1970s-inspired aesthetics with modern dimensions. This model is a limited edition of 99 pieces. On balance, owners rate the Massena LAB Dato-Racer highly for its successful fusion of vintage design and contemporary wearability.

Horage Omnium K2

The Horage Omnium K2 is lauded for its slim 7.95mm profile and chronometer-certified K2 micro-rotor movement with a 72-hour power reserve. Reviewers note its technical innovation, including a proprietary silicon escapement and modular K1 movement, and praise its value. However, some find the molded, luminous hour numerals too whimsical, and the explicit mention of "silicon escapement" on the dial is considered unnecessary. On balance, reviewers rate the Horage Omnium K2 highly for its technical innovation and slim profile at its price point.
