The Ball Trainmaster Cannonball II: The Dress Chronograph with SpringLOCK
The New BALL Cannonball II with SpringLOCK.
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. http://forums.watchuseek.com/f239/eric-singer-springlock-test-results-880532.html
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 perlage on the bridges and baseplate, a patterned rotor, and blued screws. The SpringLOCK cage is the gold colored disk inside the gold colored balance wheel.

Aside from what's under the hood, there are several aesthetic differences that will attract buyers to the new SpringLOCK. The first thing that people will notice that's different is the color. The Cannonball II is an attractive slate gray, which is a new color for the series. Additionally, the cyclops magnifying the date wheel seems more refined than the Cannonball I. The shape of the cyclops cut-out has switched from square to circular, and there is a steel colored rim around the edge. Looking at them both, I found it easier to pick out the date in the new version. The Lume of the CannonBall II is also greatly improved. Unlike the "pip" style tubes of the Cannonball I, the tubes are placed lengthwise on the II. The greater surface area, gives us one of the better lume views there is for a T25 watch.
the subdial hands are blue and the subdials feature an attractive guilloche pattern.
The cyclops magnified date is on the dial right above the Ball Logo.
The tritium tubes that serve as the hour marker are placed length-wise and offer considerably better lume than the previous version.

The Black dial CannonBall I has the "pip" style tritium tubes and a less refined date magnification.
Like the previous version of the Cannonball, the seven O'clock Marker of the Cannonball II says made of Ball & Co.
The Cannonball II has the identical case to the CannonBall I. Both watches are 43mm pieces that feature a 21mm lug width.The Topper Blog consists mainly of original writing by Rob & Russ Caplan with occasional special contributions and interviews.
