The Seiko Prospex Speedtimer Solar SSC817P1 is part of the iconic Speedtimer line and Seiko has taken the classic design and updated it with a contemporary flair and materials. With it's 39mm diameter case (excluding crown) and 45.5mm lug to lug distance the SSC817P1 is a very comfortable and most of all stylish wrist companion. Of course the watch is water resistant to 100m and the beautiful dial is protected by a sapphire crystal. The movement powering all this is the Seiko Cal. V192 chronograph movement, which is solar powered and accurate to approximately 15 seconds per month and a battery life up to 6 months. 

All in all the Speedtimer is still as relevant as it was nearly 60 years ago. Iconic.
