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.

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
