Overview

Ball Roadmaster Marine GMT Automatic Watch with Blue Dial.

The blue-dial Roadmaster Marine GMT puts home and destination time together on the wrist, framed by a bidirectional ceramic bezel chosen for strength and durability. Limited to 1,000 watches, this version pairs a 40 mm titanium case with a stainless steel and titanium bracelet and foldover clasp.

A COSC-certified Ball RR1203-C automatic caliber provides a 42-hour power reserve, running at 28,800 vibrations per hour with 25 jewels. The case is 14 mm thick, with anti-reflective sapphire over the day-and-date display and sapphire glass at the back. The hands, indices, and bezel are illuminated, with 28 micro gas tubes for night reading. A screw-down crown accompanies the 20 atm water-resistance rating, 5,000 Gs shock resistance, and magnetic protection to 4,800 A/m.

With over 15 years in the luxury market, we guarantee the authenticity and quality of every piece we sell.

Your order arrives brand new in its original Ball packaging, with all official documentation and the Ball warranty card, stamped and dated by us.

The warranty covers manufacturing defects. It doesn't cover normal wear and tear or accidental damage — and on watches, it doesn't cover straps, bracelets, or batteries.

"In stock, ships within X days" — the item is held at our secondary warehouse. We allow a few days to inspect and authenticate it before it ships.
