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.

Cincinnati Watch Company P-40 A-11 Pilot Black Automatic

Owners widely praise the Cincinnati Watch Company P-40 A-11 Pilot Black Automatic for its sharp finishing, textured pearlescent dial, and excellent lume. The simple, understated design and comfortable 38mm size are also frequently highlighted. Some owners note the bracelet lacks quick micro-adjustments and the quick-release spring bars can dig into the wrist. One owner found the lume blocks potentially thinner and the font on larger numbers less desirable than a standard typeface, though the seconds hand was considered a success. Overall, owners highly recommend the Cincinnati Watch Company P-40 A-11 Pilot Black Automatic for its great craftsmanship and value.
