Bulova Oceanographer GMT 98B407 Men's • Automatic Movement with GMT • Sapphire Crystal

The Bulova Oceanographer GMT 98B407 is a sporty men's wristwatch built for true adventurers. The 41 mm stainless steel case with grey ion plating gives the watch a bold, rugged character. The unidirectionally rotating black-and-white bezel enables precise timing during dives and expeditions, while the screw-down crown ensures water resistance to 200 metres.

The white dial of the Oceanographer GMT 98B407 is fully luminescent: the hour and minute hands as well as the applied round hour markers glow reliably in the dark. A black 24-hour scale and a date window further enhance legibility. The double-domed sapphire crystal protects the dial from scratches. The automatic movement Calibre 9075, featuring 24 jewels and a 42-hour power reserve, drives the watch reliably without a battery. The GMT hour hand can be adjusted independently, allowing simultaneous display of a second time zone. The watch sits securely on the wrist thanks to the black polyurethane strap with a robust triple-fold clasp.
