What's the time Mr Wolf? I have no idea - the best watches you can't tell the time on

As owner of a watch that you need a degree to work out the time on, I can appreciate a good non-practical timepiece. They might involve maths, the presence of a particular type of light or just good eyes, but there's no feeling like the dread you get when someone asks you the time. Get yours now.

1. Philippe Starck for Fossil
"the hours are displayed as numbers while the minutes are displayed in segments. As time goes by, the segments build making a complete ring every hour". Nope, I don't get it.

2. Tokyo Flash Shinshoku
I could have made this story up of entirely Tokyo Flash watches, since non-readable watches are what they specialise in. However I'm limiting myself to just the one, and this is it. This watch is great for those who don't care too much for being prompt, since apparently it's very easy to see "roughly" whether it's quarter past, to, half past or on the hour.

3. NOW
Wear this and people will either think you're so post-post-post-modern, or they'll think you're a bit of a twit. I can't guarantee which will happen, but luckily it comes with one of those handy strap things, so if it's the latter you can take it off.

4. Dice Guru
This one only just scrapes into the unreadable catagary, but I'm convinced that you wouldn't just be able to glance down at your wrist and see the time on it. It's available in gold, black and silver.

5. Binary Red Sumui Moon
I couldn't possibly end this without including a binary watch. I own a binary watch, and I defy even those with doctorates in computer science to tell the time in under 3 minutes. It's an especially fun game when you've had a few drinks and you're trying to work out what time the last bus goes, trust me.
