Enough with the faceless watches, you say (passim here, here, and here)? Well, check out this wall clock instead. One for very special mathematicians.
No more 9 o'clock, but 21 (4) o'clock. No more 6 o'clock, but 3! o'clock... See what we are doing here? Base 4 and factorials were never so much fun!
The crème de la calculation is ol' midnight (or midday, as some know it): 3√1728.

Okay, whats quarter-past seven in numerist time? (see below for a full 'cheat list' for the hours).
Unusable, surely, but as with most items in this series, I'm glad someone does make this beauty! The Geek Clock will set you back $25 (there's also a wrist watch version available - "It's Half-Past a Binomial Coefficient"). Check out the video:
"Cheat Sheet"
12 - A radical
1 - Legendre's constant is a mathematical constant occurring in a formula conjectured by Adrien-Marie Legendre to capture the asymptotic behavior of the prime-counting function. Its value is now known to be exactly 1.
2 - A joke in the math world: An infinite number of mathematicians walk into a bar. The first one orders a beer. The second orders half a beer. The third, a quarter of a beer. The bartender says, "You're all idiots," and pours two beers.
3 - A unicode character XML "numeric character reference."
4 - Modular arithmetic, also known as clock arithmetic, is a system of arithmetic for integers, where numbers "wrap around" after they reach a certain value. The modular multiplicative inverse of 2 (mod 7) is the integer /a/ such that 2*/a/ is congruent to 1 modulo 7.
5 - The Golden Mean...reworked a little.
6 - Three factorial (3*2*1=6)
7 - A repeating decimal that is proven to be exactly equal to 7 with Cauchy's Convergence Test.
8 - Graphical representation of binary code.
9 - An example of a base-4 number, which uses the digits 0, 1, 2 and 3 to represent any real number.
10 - A Binomial Coefficient, also known as the choose function. 5 choose 2 is equal to 5! divided by (2!*(5-2)!)
11 - A hexadecimal, or base-16, number.
