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.

Spinnaker Fleuss GMT

Owners widely praise the Spinnaker Fleuss GMT for its aesthetic appeal, comfortable and light wearability, and value, especially when discounted. The textured blue dial, applied lumed markers, and sapphire crystal with AR coating are highlighted as stunning features. Owners also note the dial is very well lumed and the bracelet has helpful quick-release tabs. However, the 43.3mm case size is criticized by some as being too large, and the Beads of Rice bracelet is described as "jingly jangly" with a pressed clasp and a clasp that isn't finely finished. Some users flag the internal bezel rotates too easily. Overall, owners rate the Spinnaker Fleuss GMT highly for its aesthetic success and value at its affordable price point.
