What reviewers and owners say
Reviewers
From 2 reviews we read or watched.
Both reviewers who handled the SN0134 liked the gradient sandwich dial (both had the purple one), the gold-toned lume, the sapphire-topped bidirectional 24-click bezel with a tight action, and the fit of the 40 mm case. One was surprised by how bright and long lasting the aged-looking lume is. Complaints were minor and each came from one reviewer: the white date wheel clashes with the warm dial colours, the AR coating glares in direct sunlight, and the arrow tip of the GMT hand is very small, although the other reviewer found the coloured tip easy to read.
