Bulova Oceanographer Devil Diver GMT Automatic Watch - 98B407

Bulova Oceanographer GMT 98B407 – A robust diver with a GMT complication

The Bulova Oceanographer GMT 98B407 was designed for the modern adventurer who demands precision, style, and reliability. The 41mm stainless steel case with a Gun IP finish combines robustness with a sophisticated look, while the black and white unidirectional bezel reinforces the model's sporty character.

The fully luminescent Natulite dial offers excellent readability even in low-light conditions, displaying a black 24-hour scale, applied indices, and a date window. The robust hands, also with luminescent treatment, ensure clear reading in any environment. The screw-down crown and screwed case back contribute to water resistance up to 200 meters, making this model reliable for diving or outdoor adventures.

Inside, the Miyota 9075 automatic calibre with 24 jewels features a GMT complication, allowing two time zones to be tracked simultaneously. With a 42-hour power reserve, manual winding, hacking function, and a frequency of 28,800 vibrations per hour, the movement combines mechanical tradition and high precision. The grey silicone strap, with a width of 20mm and a robust three-piece clasp, provides comfort and security for daily use.
