My EDC watch is a Marathon quartz from Countycomm.com. They are currently sold out, but they regularly restock. You can also find this watch on eBay.
It's the basic military issue watch. NSN 6645-01-318-9833.
Expect to pay about $100. Tritium capsules in the face and hands, so it is easily read in the dark. I can read this watch at night even when my other hand is busy or disabled.
On the band is a Suunto Clipper compass. It isn't readable in the dark without some other light source. Even the model with a luminous bezel isn't really readable. However, it works well otherwise and is always there.
Black watch with a black face on a black nylon band doesn't get much attention, whether in T-shirt and shorts or a business suit.
