It is claimed that the ceramic body is five times harder than steel and this is the precise reason why Nixon has chosen to use this material for their latest 51-30 model. In the heart of the watch lies a three hand Swiss made mechanical automatic movement with date, sweeping seconds and 25 jewels. The most impressive is the all white custom 300 meter ceramic casing and wrist bands with stainless steel skeleton. Completed with rotating ceramic bezel with count down timer, scratch resistant sapphire crystal, custom numbered caseback with hardened mineral crystal. Lastly a happy little feature for people who wear watches on their left hand is the reversed screw crown on the 9 o'clock position.
