Seiko sees whether it can command close to £5,000 for latest limited edition dive watch

It has history, being based on a 1968 saturation dive watch. It uses the highly respected and inhouse manufactured Caliber 5R66 Spring Drive GMT movement, which is accurate to +/- 15 seconds per month and has 72 hours of power reserve. And it has style thanks to a striking graduated dial that fades from black to blue in the way the earth appears when seen from the blackness of outer space.

And it is limited to a production run of 400 pieces for the whole world, which is designed to generate fear of missing out among enthusiasts.

Other high end features include  a screw down crown and Titanium 44.8mm case and bracelet. The watch is water resistant to 100 metres.
