Beautiful....

### ⭐⭐⭐⭐⭐ Great watch great value
*by C***E on 4 January 2016*

A great robust watch for someone who likes something a little bit different. Bought in red, which isn't as bright as the picture but a nice pillar box red nonetheless. In some respects a 'neutral' colour that can be worn with any outfit. Substantial watch with chunky face and good solid strap. Comes in a great presentation tin within a box. Made a fantastic present. Great value (£49.99) for a good reliable brand which can withstand the knocks of everyday life.
