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.

Hamilton Jazzmaster Slim Auto

The Hamilton Jazzmaster Slim Auto is praised for its elegance, light weight, and impressive leather strap, offering a classy yet engaging aesthetic. Its thin 8mm profile, achieved partly by omitting a seconds hand and utilizing the ETA 2892 movement, contributes to its wearability. However, one owner notes the 44mm case size as being very large, and another finds it less appealing than vintage Hamilton models, though the black dial version is considered better looking. Overall, owners appreciate the Hamilton Jazzmaster Slim Auto for its slim profile and elegant design.
