Grand Seiko's 60th Anniversary Deep Diver SLGA001 Watch Review

Posted by Daniel Luczak on 17th Apr 2020

Many people love Grand Seiko watches, and these watches are built to exude excellence, performance, and class. Everything from the house of Grand Seiko is widely popular among watch enthusiasts around the globe. On the company’s 60th anniversary in 2020, the company decided to reinvent man of their previous models and offer a wide range of beautiful watches to their audiences.

A Brief History of Grand Seiko

In the late 1950s, the masters at Seiko came together to create an unparalleled watch that would offer the highest possible level of precision, durability, and performance according to the requirements of that era. 1960 is the year they unveiled their creation, which was named, Grand Seiko. This watch was truly a “king” among watches, as it offered a superior grade of the recognized watch standard of that era.

60 years later, in 2020, Grand Seiko decided to celebrate its rich history and reinvent their famous models for modern audiences. This year, they revised the overall design and model of one of their watches and gave us Limited Edition Professional Diver's 600M SLGA001.

Limited Edition Professional Diver's 600M SLGA001

The professionals at Grand Seiko decided to offer a new method for diver watches, and the first spring drive was released in the year 1999. Since then, this technology has made significant leaps, and almost every modern chronometer uses these drives in one way or another.

Very recently, Grand Seiko announced the birth of a new movement in the Spring drive series by the name of 9RA5, and it was first introduced in SLGA001 Professional Diver's 600M. This will be a deepest-diving watch to ever come out of the house of Grand Seiko.

The Case and The Dial

The case for this watch is created from High-intensity titanium, which can easily withstand immense water pressure up to 600 meters beneath the surface. The dimensions of the case are 46.9mm (diameter) x 16.0mm (height).

The case is also quite resilient against helium interference, as divers have to worry about that when diving into deep water. All these qualities make this watch perfect for saturation diving. Moreover, the case uses a sapphire crystal as a dome. This high-clarity crystal dome keeps the display sparkling clean for maximum visibility even underwater.

The titanium used is more than 40 percent lighter than the traditionally used stainless-steel, and it is also more resilient to everyday scratches and marks.

Additionally, the power reserve indicator is at 10’o Clock (no surprise there), and it is divided into 5 different segments for a clear indication of the remaining days (5-day reserve inner movement).

When it comes to the magnificent dial of this watch, Grand Seiko decides to opt for the gorgeous Grand Seiko Blue (original) for the dial. This color is only for the limited edition version.

The Movement

As we discussed earlier, the watch uses the brand-new and self-winding movement called Spring Drive 5 Day Caliber 9RA5. With a 5-day reserve power, this movement is among the most powerful diver’s movement to date. This movement is also 0.8mm thinner than the current 9R65 caliber that the majority of Grand Seiko watches use.

It offers the dimensions of 34.0mm x 5.0mm and uses 38 jewels for optimal performance. Moreover, it offers a standard error of +- 10 seconds per month, which is quite amazing in terms of offered precision.

The Strap

The watch is limited edition, and only 700 of these are currently available in the market. These come with a beautiful blue silicone strap, which can be easily removed and interchanged with a strap of your own choice.

What Do We Have to Say?

There is no question that much has improved since the start of Grand Seiko in 1960. Grand Seiko has since introduced and evolved an amazing in-house movement for saturation divers, and the brand-new limited edition Professional Divers 600m incorporated it.

The limited-edition is not only a beautiful, precise, and durable timepiece, but it is also a must-have for the watch enthusiasts across the globe. However, only 700 lucky people can buy and enjoy this watch wrapped around their wrist.
