Dual Time. Double Impact
The Golby Aquareef truly stands out thanks to a unique twist as a Dual Timer watch, using a rotating internal chapter ring to allow the wearer to keep track of the time in two time zones simultaneously. Say you have travelled to a country two hours ahead of home, simply adjust the chapter ring using the second crown until the 2 on the chapter ring is aligned with the normal 12 o'clock position, it's as simple as that.

The Seiko NH35a automatic movement requires no batteries and is powered by the movement of your wrist, Seiko are world renowned for producing accurate and reliable movements and were the obvious choice for our watch.
