My wife sleeps (sometimes) wearing a watch. And nothing else.
I saw one article saying that sleeping naked makes good spirit to relationship and we thought to try...it became a habit and once I said as a joke that she should wear something... Took her watch and slipped it to her wrist. 
It became a habit and every now and then, mostly weekends, I manage to put her watch to her wrist when we go to bed. It is just fantastic to weak up and sleep with totally naked woman who wears men's steel watch. 
When she goes to work, I sometimes get lucky to put her watch once in a week or so. She puts her make-up, high heels, business clothes and parfume. (I have a HUGE fetish also for business ladies...) and then she walks to our bedroom. I am waiting there totally naked, on my knees and she gives her hands to put her jewellery and watch, and as reward she gives me a handjob while I am watching and kissing her watch...
With these cases she mostly wears big 45mm Michael Kors or mens size Tag Heuer Aquaracer.....
