The baby tuna is an automatic watch. It comes with 24 jewels
, ensuring its gears work as smoothly as possible.
Not all of us are watch nerds, and you may be wondering why the Baby Tuna has jewels in it
. Well, this addition keeps its gears frictionless.
Since it’s an automatic watch, a self-winder is always handy. Luckily for you, you get such a feature with the Baby Tuna.
Even though winding is a feature you’ll appreciate, you may like want to hack the watch as well. With the ability to hack
, you can adjust the Baby Tuna’s hands, making the time more accurate.
According to Seiko, the watch ‘maintains accuracy for 30 seconds a day
’. That’s great, but we’re disappointed this differs per conditions the watch is used in.
We’ve mentioned that it’s automatic and has 24 jewels, but what type of automatic mechanism does it have?
If you’re wondering, the Baby Tuna is a 4R36. Seiko’s 4R36
allows it to have a day date function. This makes life easier for you as you’re always ahead of things.
The watch has a case that’s on the thicker side: it’s 1.88 inches (48 mm). Many people are a fan of watches this chunky as they have a specific feel. Are you one?
With a 1.88 inches (48 mm) case
, your wrists may feel a bit heavy but this comes with a benefit. Being so thick, the case can take a beating. So if you’re clumsy, you don’t have to worry.
The fact that it’s scalloped shaped
helps with comfort as well. The shaping fits your wrist perfectly.
Its chunkiness isn’t the only durable thing about the case. It has a stainless steel covering
, keeping scratches at bay.
Yes, the addition of stainless steel is great but at the end of the day, this isn’t something we haven’t seen before.
The Baby Tuna has an extra hard coat. This is in either black or blue (but this may only be present in certain models).
Similar to the case, its bezel is stainless steel with an added hard coat.
As the watch is fit for diving, the bezel was made accordingly. Users have noted that it’s easy to rotate
which makes life easier underwater.
It ticks every 15 seconds for its Arabic numerals and 5 for its white markings.
Moreover, we find it cool that the bezel has fin-like markings on its side, it’s very retro.
The dial is very beautiful. From the many watches I’ve seen, the Baby Tuna is one of the best looking automatic watches out there.
Its display is pitch black, having gold accents throughout. The gold is in the hands and markings. Although it’s a deep black, the markings and hands are white with a gold border. The combination of all 3 colours makes it very appealing to the eye.
That being said, there’s a downside; its markers are quite big. This makes it very busy looking. Due to the bunching up of everything, reading time can be an eye strain.
The size of the markings is to make reading easier, because of the watches lume
. It allows for more than enough space for the LumiBrite
. As you can imagine, this makes the watch impeccable underwater and in the darkest environments.
If you’re not a Seiko fan, you probably don’t know how great its LumiBrite is. It can glow up to 5 hours fully charged. Being able to last for so long is awesome, but you can only charge the lume through sunlight.
Although it’s a limitation, it will not a problem as you don’t live in a cave, do you?
Having LumiBrite, the watch would light up even if the room is dimly lit.
If you’re interested in what type of material its display window is, it’s hardlex crystal
. This material lets you keep scruffs at bay.
Many use the Baby Tuna as their go-to dive watch. Why?
Firstly, it can last up to 660 feet
(200 m) underwater. This means it’s perfect for snorkeling. Seiko ensured the watch would be functional when submerged. This is as it is ISO 6425 certified.
Second, the fact that its crown is sealed and that it has a unidirectional bezel makes diving easier.
And thirdly, the Baby Tuna has a stainless steel strap
. Although it isn’t the most eye-catching, it’s a material perfect for underwater use
. It's corrosion-free and is easy to maintain; perfect for the lazy!
Also, Polyurethane is comfortable on the skin.
The Baby Tuna is not the cheapest dive watch out there. It’d be great if it had a helium valve as cheaper watches have this feature. If you’re not aware of what a helium valve is, it helps relieve gas pressure as you resurface.
