Trainmaster Cannonball CM1052D-S7J-WH

SWISS-MADE LUXURY. WORLD-READY TOUGHNESS.

Ball designers took a bold step to modify the movement from 30 minutes elapsed time to 45 minutes chronograph. Additional jewels were added to ensure the smooth running of this complication through lowering the friction between surfaces, resulting in a complex 49-jewel movement. Compared with a typical movement of minimum 17 jewels, the creation of this special caliber is a labor-intensive process that requires greater skills. The sapphire exhibition case back of the Trainmaster Cannonball gives you a glimpse into this mechanical beauty.
