Tudor Black Bay GMT
The 41 mm stainless steel case has a brushed and polished finish, offering durability and presence without compromising on comfort. It is water-resistant to 200 metres and topped with a domed sapphire crystal.
The bidirectional bezel is anodised aluminium in the iconic red and blue “Pepsi” colour scheme. It displays a 24-hour scale for quick reference when tracking a second time zone with the dedicated GMT hand.
The dial is matte black with large applied hour markers filled with Super-LumiNova. Snowflake hands, a hallmark of Tudor design, ensure excellent legibility in all conditions. The red GMT hand stands out against the black dial, making dual-time reading effortless. A date window sits neatly at 3 o’clock.
Inside is the in-house Tudor calibre MT5652 automatic movement. This COSC-certified chronometer offers a 70-hour power reserve, a silicon balance spring for anti-magnetism, and a bidirectional rotor system.
The watch is fitted with a solid stainless steel riveted bracelet, secured by a folding clasp with safety catch.
The Tudor Black Bay GMT 79830RB combines vintage-inspired styling with modern performance. Its Pepsi bezel and robust build make it a versatile choice for both collectors and travellers.
