The emperor tuna! The best way to describe it is to call it a Rolex in a tuna can. Besides looking so good, its also driven by the best Seiko has to offer.

Using Seiko's 8L35 movement which beats at 28800 vibrations per hour, the accuracy of this masterpiece is remarkable at +15 to -10 seconds per day.

The reason behind this remarkable accuracy is obvious. The 8L35 movement by Seiko is used in Grand Seiko models as well!


                                 
The emperor tuna lives up to his name by also being huge. Measuring 52mm in case diameter is not why its so huge. Its huge because of its 17.4mm case thickness!! Imagine how huge it is compared to the already big sumo with 13.5mm thickness. So if you're thinking of formal wear with this watch you can probably dismiss that thought right now.

But its perfectly understandable why it has to be so thick. It has to withstand the immense pressure at 1000m deep underwater. How can any normal watch do that?


As usual, Seiko's Lumibrite technology never fails to amaze me.
                                       

Its lume is able to glow like stars with just a little light exposure. The lume on this will last 3-5 hours with just a little bit of natural lighting. I really like how Seiko is not stingy with the paint on the hands and the indices.


Although I do not currently own a Seiko Emperor tuna because its obviously not cheap, I will probably work towards one and hopefully get it one day! In my opinion, probably one of the best dive watches you can get your hands on. If you can afford, don't hesitate!
