SEIKO's unique technologies

New balance spring made with SPRON610

For safe use by divers at depth, the watch movement as well as the case must be extremely robust. For this new Ananta creation, SEIKO re-designed its 8R movement, incorporating a balance wheel made of SEIKO's proprietary alloy “SPRON 610” which is stronger and more durable than any other SPRON alloy. To ensure that the watch is as resistant as possible to shock, it is fixed to the case in three places, one more than is used in other chronographs.
