"An aesthetic and timele no date "Looks absolutely stupendous..." - NS PR In response to some requests for a Vietnam /Platoon style Special Forces / UDT watch we have been able to offer this model. This model is brought to you by QM with the same high quality you have come to expect from Cooper Watches. Also have a look at the new green and blue colours which are very aesthetic. The Seiko VH movement has a 2 year battery life and ticks 4 times per second. So the sweep isn't as smooth as your typical modern mechanical movement (affordable Seiko mechanicals like the Seiko 5 and Cocktail Time usually tick 6 times per second). If you love vintage mechanical watches that tend to beat/tick at lower frequencies, you will love the sweep of the VH movement along with quartz accuracy.
