Geeks: We've Got Your Number

Regular numbers? Those are for amateurs. This stylish design is a clever math ethusiast's alternative to traditional watches with equivalent notations for each number. Finished with a slender nylon wristband, you'll bring out your inner genius with elegance. :
1: i is equal to the square root of -1, so i^2= -1. The absolute value of -1 is 1.
2: This represents 2 in binary code.
3: The cube root of 27
4: 11 base 3, which represents 4 in the ternary system
5: Log(20x)=2 is equivalent to 20x=10^2 or 20x=100, where x=5.
6: Euler's product formula: phi(p^k)=(p^k)(1-(1/p)), where (p^k)=9
7: This is a binomial coefficient, so with the formula n/k = (n!)/((k!)(n-k)!), n/k=7.
8: This is a natural logarithm where ln(e^x)=x, so ln(e^8)=8.
9: This summation is equal to 3(1)+3(2)=3+6=9.
10: Since clocks "wrap around" every 12 hours, the hour number starts over after it reaches 12. This is arithmetic modulo 12. 10mod12 is 10:00, and 16mod12 would be 4:00, for example.
11: B'L is Legendre's constant, which is equal to 1, so this equation becomes the square root of 121, which is 11.
12: Hexadecimal representation of 12

Made in China. Japanese movement. 3 ATM water and splash resistant.

Alex Goldberg designed and made watches and accessories for various retail chain clients for over 10 years. In 2001 Alex designed his own line of watches. Watches that told the time, yes, but would always do something more (after all, no one really needs a watch these days if you are only interested in knowing the time of day). Alex’s watches incorporate celestial bodies, ancient instruments, color and light to create watches that just do not simply tell time, but tell a story and tell you a little something about the person who chooses to wear that watch.
