The Prospex Story:
Scuba-diving became increasingly popular around the 1960’s, an example of this was the formation of the Professional Association of Diving Instructors (PADI) in 1965. Moreover, diving equipment was becoming increasingly reliable, so more people began to dive recreationally. There was of course a crucial need for divers to be able to time their dives. Subsequently, the watch market responded to this necessity by flooding the market with reliable dive watches.
In 1965, Seiko first produced their original dive watch – the 6217. This was the very first Japanese dive watch and it paved the path for future divers that claim to meet Seiko’s Professional Specifications. The original 6217 was notably worn by the 8th Japanese Antarctic expedition. This model featured bidirectional rotating bezel, legible lumed hands, and an easy-to-grip crown.
Although professional divers were still pining for a dive watch that had the capability of going deeper than 300 metres. The Seiko development team went about going to produce a watch which was capable of doing so. The year 1975 marks the release of the first Seiko Prospex, with the ability to be used in 600 metres of depth. The Prospex is the first diver watch to use a titanium case instead of standard steel. It was also the first to use a ceramic shroud for deep-sea diving and the first to use a hybrid analog digital watch with an alarm.
Another achievement for the Prospex family was the L-shape single crystal gasket, which prevented any helium escape valve unnessacary. This was one of the development teams first aims, to prevent a helium resistant watch. There were numerous other milestones that Seiko achieved with the Prospex. Such as in 1986 when Seiko produced a watch that was water resistant to 1000 metres.
The Brand: Seiko
Seiko’s story began in 1881 with the opening of a shop in Tokyo, it’s owner was Kintaro Hattori. Eleven years after the opening of his shop, Hattori opened a clock factory 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. Then in 1924, the brand Seiko was born with the creation of the first Seiko wristwatch.
Seiko established itself throughout the 20th century as being a force in the advancements that took place in the watching world. For example, Seiko were the producers of the first winding wristwatch made in Japan. Then in 1964, Seiko became the official timer for the 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.

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.
