What people say

Owners + reviewers, side by side

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

Sternglas Naos XL

Owners widely praise the Sternglas Naos XL for its versatile Bauhaus design, domed sapphire crystal, and value, with some finding its larger size comfortable and refined for its price. However, opinions are split on its aesthetic appeal, with one owner finding the hands and face underwhelming, while others appreciate the minimalistic dial. The date font is noted as too small to be useful by one owner, and the stock strap is generally considered basic or prone to wear. Accuracy figures vary, with one owner reporting a Miyota movement running fast and another noting +13 seconds per day. Overall, owners rate the Sternglas Naos XL highly for its Bauhaus aesthetics and affordability, despite some reservations about the movement and strap.

Yema Superman Tourbillon CMM.31 Limited Edition

Owners praise the Yema Superman Tourbillon CMM.31 Limited Edition as an incredible and crazy watch, appreciating its unnecessary tourbillon complication and impressive specifications at a remarkable price point. The titanium construction contributes to comfort despite the 43mm case size. One reviewer notes the bracelet clasp's extension system is somewhat crude. On balance, owners and reviewers rate the Yema Superman Tourbillon CMM.31 Limited Edition highly for its compelling tourbillon feature at an accessible price.
