From the Interwebz:
"The MUSK MR2129 is being billed as the world’s largest commercially available wristwatch – and by the looks of things I wouldn’t doubt it.
The MUSK watch clocks in at an absolutely retarded 715 grams ( 1.58 lbs ) with a diameter of 9cm ( 3.5 inches ). Its features include an onboard thermometer along with all of the standard wristwatch fare.
If you would like to make a clear statement with your choice of wristwatch - namely, “I have no taste†and “I have a serious farsighted vision problem,†you can pick up a MUSK MR2129 from the
product site (Japanese Translated ) for ¥24900 ($208)."
