BALL's SpringLOCK technology, is rolling out in three models this month: The Cannonball II, Hydrocarbon Airborne, and Spacemaster Blackrock. While the latter two watches are both sport watches, the Cannonball II is the only dress watch coming this fall that will feature this new technology. Aside from providing the more robust SpringLOCK technology, the Cannonball II has a lot to offer as it combines an attractive new gray dial with a few refinements to the Cannonball I's design.
SpringLOCK, is Ball's proprietary innovation that protects a watch movement's hairspring. The hairspring is the most vulnerable component in a mechanical watch, and the main reason why even high-grade chronometer movements lose accuracy when exposed to mild repetitive shock. We discussed the effectiveness of SpringLOCK in June when Kiss Drummer Eric Singer tested two SpringLOCK equipped prototypes and my Engineer Master II Skin Diver as a control.

During the concert, The two SpringLOCK watches were exceptional while my SkinDiver lost a great deal of accuracy.
The Cannonball movement is an attractive setting to provide the first production view of SpringLOCK. The movement features pearlage on the bridges and base-plate, a patterned rotor, and blued screws. The SpringLOCK cage is the gold colored disk inside the gold colored balance wheel.
