Analysis
The Good & The Bad
What We Like
- Scratch-resistant sapphire crystal
- 1000m water resistance — true dive watch spec
- Seiko NH35/NH36 — reliable, widely serviceable Japanese automatic
- 316L surgical stainless steel case
- BGW9 Super-LumiNova — bright blue-green glow
- Ceramic bezel — scratch-proof and fade-resistant
What Could Be Better
- NH35/36 accuracy is -20/+40 sec/day — you'll adjust time weekly, not COSC-grade
- 49mm case diameter — will wear large on wrists under 7 inches
- 316L steel is durable but heavier than titanium — noticeable on long wear days
