The DS Trust is a square ETA quartz powered Swiss watch.  It's a great way to add some variety to your collection and it easily dresses up or down.  The 8.6mm thickness allows it to disappear under a sleeve very well and it also looks great with a T-shirt and some jeans.  It is 34mm across, but since it is a square watch it really wears like a 39 or so.  I have always taken good care of it and it is in excellent condition as you can see in the photos.
Certina lists this watch as the lady's version.  This is exactly the same size as the "Men's" version, also a 44mm but in Titanium instead of stainless steel.  I'm a man and have worn it plenty and believe me it doesn't look any more feminine than the Men's version, just a lighter colored bracelet and dial.  This was bought through Jomashop so it comes with an off brand box, but has the manual, warranty card, hang tag, etc. from Certina.
