The Bulova Devil Diver GMT is a family of Oceanographer watches, not one single colorway. The reference number identifies which one you are looking at: 96B405 pairs a blue dial with a blue-and-red bezel and steel bracelet; 98B407 has a luminous white dial, black-and-white bezel and silicone strap; and 97B215 combines rose-gold tone with a black dial and two-tone bezel. Bulova lists all three with 41 mm cases, 200 m water resistance and 42-hour power reserves.
What does “Devil Diver GMT” refer to?
Bulova Australia explicitly uses “Automatic Oceanographer Devil Diver GMT” for references 96B405 and 98B407. The 97B215 appears under both “Oceanographer GMT” and “Automatic Oceanographer Devil Diver GMT” naming on Bulova pages. Since the family name alone does not identify the finish or strap, check the reference number when comparing listings.

Bulova’s account of the Oceanographer’s history says the original model was rated to 666 feet, a figure associated with the “Devil Diver” nickname. That is Bulova’s historical account, published January 10, 2024, rather than independent historical verification. Bulova’s Oceanographer collection and the individual product listings provide the current family and model names.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals.

What specifications do the models share?
Bulova specifies a 41 mm case and 200 m water resistance for each of the three references. The brand also lists a self-winding, 24-jewel GMT movement with a 42-hour power reserve for these models. Those are manufacturer-stated specifications; they should not be read as results from independent testing.
Each model has a screw-down crown and a date display. The 96B405 has a box sapphire crystal, as does the 98B407; the cited 97B215 description does not state its crystal type. That difference in available detail is not evidence that the 97B215 uses another material.

How does the GMT hand work?
Bulova describes the hour hand as independently adjustable to set local time. Its product description for the 96B405 says, “An independently adjusted hour hand allows for easy setting of the local time.” The brand’s article on the 97B215 says its GMT function can track two time zones.
