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.

Grand Seiko SBGH263

The Grand Seiko SBGH263 is praised for its excellent finishing for the price, with reviewers comparing it to Jaeger-LeCoultre. Owners and reviewers highlight the stunning 'Shironeri' dial and gold hands/numerals, and the 39.5mm case size is considered a perfect fit, referencing vintage Grand Seiko models. The watch features a 55-hour power reserve from its 36,000 BPH movement, though one reviewer felt the date aperture was unnecessary. On balance, owners and reviewers rate the Grand Seiko SBGH263 highly for its exceptional dial and finishing at its price point.
