Analysis
The Good & The Bad
What We Like
- Scratch-resistant sapphire crystal
- 400m water resistance — true dive watch spec
- Seiko NH35/NH36 — reliable, widely serviceable Japanese automatic
- C3 Super-LumiNova — strong green glow
- Ceramic bezel — scratch-proof and fade-resistant
- 40mm case — versatile wrist presence
What Could Be Better
- NH35/36 accuracy is -20/+40 sec/day — you'll adjust time weekly, not COSC-grade
