Ball Watch, which develops robust and highly reliable practical mechanical watches, began selling its "Roadmaster" series, which had not previously been available in Japan, in December. The first in the series is the "Roadmaster Marine GMT," which features a GMT function that allows you to keep track of up to three time zones thanks to a 24-hour hand and a bidirectional rotating 24-hour bezel. At 290,000 yen (excluding tax) for this quality, it is likely to attract attention among the many rival mid-range sports watches.
The mid-range killer has finally been released
A GMT mechanism like a luxury watch
The greatest feature of this watch is its easy-to-use GMT function. While the 24-hour hand is usually adjusted using the crown, it can now be adjusted using two pushers on the left side of the case. The 24-hour hand, with its skeletonized tip, moves back one hour with the pusher at 8 o'clock and forward one hour with the pusher at 10 o'clock. This special mechanism was developed by Phi Van Tran, head of Ball Watch's R&D department, Patrick Lab. It was realized by combining a unique module based on the SW220-1 caliber. This is a mechanism that Phi Van Tran is proud of, having previously brought innovations to Greubel Forsey and Péquigne, and having worked on Ball Watch's first in-house movement.

GMT with a choice of three bezel types

While there are no time limits for push button operation, simultaneous operation of two push buttons is prohibited, as well as operating the crown. Featuring a lightweight, rust-resistant titanium case with a bold finish, 200m water resistance (as the model name suggests) for use in the ocean, shock resistance (5,000Gs)—a rarity among mechanical watches—a Swiss COSC-certified chronometer movement—proof of high precision—date and day display for business use, a luminous ceramic top bezel with color-coded 24-hour time zones, an anti-reflective sapphire crystal that maintains visibility even in strong sunlight, and a self-luminous micro gas light that makes reading the time in the dark—this is a highly satisfying watch that pursues both functionality and practicality.

The watch features a built-in module and a sapphire crystal case back, all of which are just 14mm thick. The bracelet is made of a combination of titanium and stainless steel, optimizing the specific gravity balance.
Equipped with 27 self-luminous micro gas lights on the hands and dial

The bidirectional rotating bezel's 24-hour display ring allows you to see the time in three different countries. The micro gas light, which is 70 times more luminous than Super-LumiNova, emits green and orange light, making it easy to tell the time even in the dark.
