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.

Nodus Sector II GMT

Owners and reviewers widely praise the Nodus Sector II GMT for its versatile, refined design and surprisingly good finishing for its compelling price point. The watch features a regulated Seiko NH34 movement, running at +5 seconds per day according to one review, a sapphire crystal with AR coating, and 100 meters of water resistance. Some owners wish for lume on the GMT hand and prefer a bi-directional GMT bezel over the 120-click dive timing bezel, while others find the NH34 movement overpriced for the cost. On balance, owners and reviewers rate the Nodus Sector II GMT highly for its refined design and impressive finishing at its price point.
