The Ball Trainmaster series took a turn from Ball’s conventional sporty design and featured artistic decluttered dials. It’s also the collection that has dedicated watches for women with gas tubes decoration in it. The use of golden dials and antique symbols makes this collection one of the most expensive ones. It starts at a price of $1,000 and goes all the way to $10,000. Exquisite Timepieces is an authorized dealer of the Ball Trainmaster collection. You can find Ball Trainmaster watches for sale here.
