What people say

Owners + reviewers, side by side

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

Zelos Nasa Edition (sellita)

The Zelos Nasa Edition (sellita) is praised for its thinness, stemming from its hand-wound Sellita SW215 movement, and is noted for its good size and wearability. The watch features a 39mm case, a 45mm lug to lug, and a 20mm lug width. On balance, owners rate the Zelos Nasa Edition (sellita) highly for its comfortable dimensions and thin profile.

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.
