Community Reviews

Deep Blue's Daynight comes across as a strong value tritium diver with sapphire crystal and an automatic Seiko NH35 movement. The brand's build quality and accuracy get praised, and the price looks especially sharp versus similar tritium watches or quartz alternatives. The carbon fiber reinforced polymer case is not metal, and the bezel and dial layout can feel crowded at a glance. It stands out most for buyers wanting a unique white faced automatic diver with tritium.

Common Questions (5)

  • Yes, it is described as a strong deal for tritium and sapphire crystal, especially at this price. The automatic movement and Deep Blue's microbrand reputation add to the value compared with similar quartz options.

  • The listing is described as an NH35 automatic, but one comment questions whether it is a genuine Seiko movement or a clone. Another comment says Deep Blue appears to have improved the movement from Miyota to Seiko NH35 on this line.

  • The listings are the same watch line with different dial colors and different tube colors. The other color options are also priced the same.

    wingtsewingtse

  • The case is carbon fiber reinforced polymer, not metal. That matters if you want a lighter case or were expecting a traditional steel diver.

    scubasasquatch

  • It is positioned as a unique white-faced automatic diver with sapphire and a Seiko movement. One caveat is that the bezel action may not be as satisfying as on some similar divers.

Solid deal with current NH35 pricing, especially being tritium. Keep in mind this is a carbon fiber reinforced polymer case, not metal. I'll probably grab one though as a donor for a mod though.

OP do you have this watch? I like the look and specs (sapphire and Seiko movement) but I don't think it cracks the rotation since I have similar divers. Would be great for someone wanting a unique white faced automatic diver

I don't, like 3chunter, I have a few from the brand - just not this model. They always seem to offer high value for dollar. Given the specs, it's hard to beat their models. You make find a Quartz version of a similar style, but not an automatic like this one.

Deep blue is a good micro brand. This is a good deal with tritium, and sapphire crystal. If I don't already own many diver, I would buy it.
The other color options are also the same price, if you like blue tritium tube

Good price for saphire and a MH35 if it's a genuine Seiko. If it's an aliexpress MH35 then maybe not. Is it me or does the combination on markers on the bezel and the face make this feel "crowded"? At a glance I feel like i"m looking at a Dart Board.
