Bremont Supermarine 300M GMT “Glacier Blue” – Limited Edition of 500 – Full Set

A striking combination of British watchmaking, sophisticated engineering, and expedition-ready design, this Bremont Supermarine 300M GMT “Glacier Blue” is a limited-edition timepiece produced in just 500 examples worldwide.

Inspired by the dramatic glacial landscapes of Iceland, this distinctive Supermarine features a captivating blue gradient dial, transitioning from rich ocean blue to nearly black. The contrasting orange-tipped GMT hand adds a bold splash of color while providing the practical ability to track a second time zone.

The bidirectional 24-hour bezel, generously lumed hands and markers, and date display at 3 o'clock make this an exceptionally functional watch for travelers, divers, and enthusiasts alike.

The beautifully finished 40 mm case is constructed from corrosion-resistant 904L stainless steel, a premium material prized for its durability and exceptional finish. A domed sapphire crystal protects the dial, while the screw-down crown and robust case construction provide an impressive 300 meters of water resistance.

Inside beats Bremont's modified BE-93-2AV automatic GMT movement, featuring 25 jewels, a 28,800-vph beat rate, and approximately 50 hours of power reserve.

Completing the package is Bremont's distinctive black rubber strap, offering exceptional comfort and a purposeful, sporty appearance.
