Hi GB109 and welcome to the forum.
Mrs Slartibartfast has a Rolex ETA DateJust two tone with CZ dial, and loves it.
Also has a TAG Link (quartz) white faced and is not so keen, though loved it at first, has gone off it.
But most favoured of all is a two tone Omega Constellation (quartz). This is a small slim well built rep that is good to go for everyday use. She has been complimented on it many times!
As you will guess there is a small watch theme running here. I am thinking about surprising her next with a two tone Cartier Santos (very nice).
Either way you jump, I am sure you will be hooked!
