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.

Boldr Globetrotter GMT

The Boldr Globetrotter GMT is praised for its legibility and finishing, featuring applied Super-LumiNova indices and sword hands on a matte black or sunburst blue dial. Reviewers highlight the ceramic bezel's sharp city markings and tight, smooth ratcheting action. The 44mm 316L stainless steel case exhibits a non-traditional design with radial and vertical brushing.
