BALL Watch Trainmaster Worldtime Chronograph Automatic Series

In 2010, BALL Watch Company presented the world’s first mechanical timepiece including a day and date function combined with a 24- hour time zone display. The “Engineer Master II Diver Worldtime” and “Trainmaster Worldtime” models were the first BALL timepieces to have a caliber with this new module developed by BALL Watch. This year, BALL Watch Company decided to extend its collection of a new model housing its universal time display module dedicated to travellers .

In its absolute respect for the values of precision, reliability and tradition of the “Trainmaster” series, the Worldtime Chronograph thus provides a worthy addition to the BALL watches combining a day and date function with the time display in the 24 hour zones.

Grafted onto an automatic ETA 7750 movement, a special module drives a disk engraved with the names of the planet’s main metropolises rotating automatically in the reverse direction to the hands, so that it simultaneously indicates the time in 24 different geographic zones. In this way, BALL Watch has relaunched the attraction for its chronograph range, ever a timeless watchmaking complication and one of the functions unanimously appreciated by mechanical timepiece aficionados. The Trainmaster Worldtime Chronograph therefore delivers the perfect combination of these two accomplished watchmaking complications.

This new model also incorporates all the features for which BALL watches are renowned. The first of these, the iconic signature of the brand, is watch’s perfect legibility even in the dark thanks to the addition of 15 micro-tubes filled with 3H gas on the hands and the dial.

Water-resistant to 50 meters and certified shock resistant up to 5,000Gs, the Trainmaster Worldtime Chronograph ably combines strength with streamlined elegance and restrained design. Available with a white or black dial, the stainless steel case can be affixed to the wrist using a crocodile leather band. An anti-reflective sapphire crystal and screw-in crown add the final demanding touches to this exceptional chronograph.
