The Dial:

The understated black dial is laid out very clearly, with large lumibrite hour and minute hands displaying local time. A smaller sub-dial at 6 indicates home time. A sub-dial at 3 indicates the day of the week on the local time, and an AM/PM indicator is set within. Another sub-dial at 9 acts as a function indicator and a power reserve indicator.  It also features the ever present Seiko logo beneath the 12 o’clock mark. A day display is also present at the between the 4 and 5 o’clock indices.


Quartz mechanisms power the watch, it synchronises twice a day to an atomic clock in a GPS satellite. The first connection of the day will be made when the dial sensor detects sunlight and the second is made at a time that is predetermined and set by the wearer, to accommodate their needs. The 5X53 caliber boasts an extraordinary time accuracy of 1 second deviation every 100,000 years making it one of the most accurate watches in the market. Although without GPS connection, the quartz movement keeps time to the standard +/- 15 per month accuracy. Also to note, the watch is water resistant up to 100 metres.

The Family: Astron 

Thanks to Seiko’s relentless drive for innovation, new possibilities in watch technology continue to open up as the new Seiko Astron, the world’s first GPS solar watch, so dramatically demonstrates. Seiko has, once again, pushed back the boundaries of what a watch can deliver and has set a new world standard in electronic watchmaking. The progress of Astron never stops. Astron has continued to pursue “the ultimate wristwatch” – The GPS Solar watch “ASTRON”.

The Brand: Seiko

Seiko’s story began in 1881 with the opening of a clock shop in Tokyo, it’s owner was Kintaro Hattori. Eleven years after the opening of his shop, Hattori opened a clock factory with ten employees and it was in 1895 that they began to produce pocket watches. Soon followed by alarm clocks in 1899, and then table clocks in 1902. Then in 1913 Hattori began working on his first wristwatch. The in 1924, 43 years after the initial opening, the brand Seiko was born with the creation of the first Seiko wristwatch.

Seiko established itself throughout the 20th century as being a driving force in the advancements that took place in the watching world. For example, in 1956, Seiko were the producers of the first winding wristwatch made in Japan. Then in 1964, Seiko became the official timer for the Tokyo Olympics. And then most notably Seiko unveiled the first quartz wristwatch, the Astron, in 1969. Marking the beginning of the quartz revolution. Or equally impressive the creation of the world’s first TV watch in 1982. And even more relevant today, with our abhorrent use of non-renewable energy sources, Seiko’s Kinetic. This watch had the ability to generate its own power from the movement of the wearer.

Ceaseless determination to innovate in every aspect of the watchmaker’s art is what defines Seiko’s 135-year history. By embracing this ethos, Seiko has been responsible for a string of industry-leading advances in the technology of time. Notably, the creation of the world’s first quartz watch in 1969. The listed technological developments serve as evidence to illustrate the revolutionary impact which Seiko has had on the watchmaking world. They are also markably unique in that they manufacture every aspect of every watch in-house.

Additional information



Free Strap Adjustment

It's important that your watch fits your wrist comfortably and looks great at the same time.

Leather strap watches tend to fit without a problem for most wearers. However, watches fitted with metal bracelets often need adjusting to get the perfect fit.

This is generally a very simple procedure. We can do this for you, or you can get the watch adjusted locally.

Option 1. Specify your wrist measurement and we will adjust it before being sent

When purchasing a watch which has a metal bracelet with adjustable links, we will gladly adjust the watch bracelet to fit your wrist before sending the watch to you - free of charge!

Simply type your wrist measurement (in inches or centimetres) into the bracelet size section of the checkout and we will ensure the watch bracelet is adjusted accordingly before being sent to you. We will include all the surplus links, with the watch.

How to measure your wrist

You can measure your wrist with a piece of string which you can measure against a ruler:

You should allow about half a centimetre (1/4 inch) of slack to prevent it being too tight on your wrist.

In the event of you needing an extra-long wrist bracelet, which requires an extension to the original watch, we must obtain extra links from the manufacturer, and in this event, we will contact you to inform you of any possible delays or applicable charges.

Watches with bracelets adjusted by WatchNation are still eligible under our refund policy.

Option 2. Buy the watch online from WatchNation and have it adjusted locally

If you wish, you can have it adjusted locally by another jeweller or key cutter. However, you will have to cover the cost of this option yourself.
