What people say

Owners + reviewers, side by side

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

Hemel HFT20

The Hemel HFT20 Chronograph is praised for its legible matte black dial, sapphire crystal, and the satisfying sweep of its chronograph hand, powered by the Seiko VK64 meca-quartz movement. Reviewers note its convenient wearability, with a 42mm case that wears well due to its 49mm lug-to-lug measurement, and a comfortable, well-made leather strap. However, its 16mm thickness is considered slightly more than ideal for the movement, and the chronograph minutes sub-dial does not precisely jump. Overall, reviewers find the Hemel HFT20 to be an accessible and modern interpretation of vintage designs, offering good value at $449.

Sternglas Naos Großdatum

The Sternglas Naos Großdatum is praised for its Bauhaus aesthetic and value, with one owner finding it an affordable alternative to other designs. However, some owners report it feels underwhelming and cheap, with a printed-on face, small font, and toy-like hands, and find the strap to be of poor quality. The watch features a 38mm stainless steel case, an Alabaster dial with beige LumiNova, and a Seiko TMI VJ76 quartz movement rated for -20/+20 seconds per month. On balance, owners and reviewers are divided, with the primary point of contention being the perceived quality and aesthetic execution of the Sternglas Naos Großdatum.
