Massena LAB Dato-Racer owners widely praise it as an excellent everyday watch, blending 1970s aesthetics with modern dimensions. This limited edition model is restricted to 99 pieces.

Sternglas Hamburg Automatik

The Sternglas Hamburg Automatik is praised for its handsome design, affordable price, and good build quality for the cost. Reviewers note its 42mm diameter wears well due to a short lug-to-lug distance. The Miyota 8215 movement is cited as accurate to -20/+40 seconds per day. Some find certain variants' designs "too much" or "garish," while others appreciate their unique, non-emulating style and "Bauhaus simplicity." Overall, owners and reviewers rate the Sternglas Hamburg Automatik highly for its attractive design and value proposition.
