Twelf-X is a newer company that, right now, has two watch models available. They have the Twelf-X Sky 1914 Auto flyer (which I reviewed back in October). They also have the Twelf-X 1908 Deep Wave diver. Since I am a diver this was a natural one for me to review, and we were able to get a loaner in.

You don’t need a lot of clutter on a diver – you want to easy read and track your time. The dial on this Twelf-X 1908 Deep Wave is simple, clean, and very legible; hour markers are very large and easy to see at a glance. The face on this is a matte blue with a textured surface. That’s about it – clean and simple, just like the dive doctor ordered. Protecting all of this is an anti-glare sapphire crystal. Hiding under that dial is the highly-used automatic Seiko NH35 movement, so it should be reliable.

The Case

The case on this Twelf-X diver is made for diving. It’s not flashy or dressy, it’s made to work. The whole stainless steel case has a brushed finish which is great for hiding the scratches you will get during diving and general abuse. Size is just right for a diver at 44mm. The 120 click unidirectional bezel has a solid feel yet it is easy to grip and rotate. It’s always good to have a backup watch when you are diving, cause of your dive computer goes out, you will need something to track your time. This case has a screw down crown and exhibition case back. Of course a dive watch needs to be water resistant and this one does well at 20bar/669ft/200m.

The Strap

Not all divers will actually head under water – many are what we would call “desk divers”, and this Twelf-X realizes that. It comes with a nice, soft, leather strap with signed buckle. I would not be going diving with that on. If you do want to switch up to a rubber strap that’s easy to do since this strap comes with self release spring bars. If your not planning on getting wet then this strap is very comfortable and looks great too.

The Lume

The lume on the Twelf-X diver looks fantastic and is very bold. All the hands and hour markers are lumed and really look great but the bezel is not. I would have liked to see some lume on the bezel, at least a lumed marker at the 12 o’clock position. Aside from that the lume really looks good.

If you are in the market for a good diver for a good price, this Twelf-X diver might be for you. Build quality is great and it looks pretty sharp. Add a rubber strap and this can he a great little diver. With a price of only $285 you get a pretty good little tool watch. If you like what you see go check them out at
