Bulova Marine Star 98A302 orologio automatico d 45mm, Blue Dial

The 98A302 makes a strong visual statement, beginning with its 45mm stainless steel case. A deep blue dial provides the backdrop for an open-heart aperture at the seven o'clock position, offering a continuous view of the automatic movement's balance wheel in motion. The hands and indices are generously sized for legibility.

Functionally, this Marine Star is governed by a self-winding mechanical movement, removing any need for batteries. While not an ISO-rated diver, its name is backed by a unidirectional rotating bezel for timing events and a water resistance rating across 100 metres. The screw-down crown contributes to this level of protection.

On the wrist, the watch has considerable presence due to its size and a weight of 220 grams. It secures with a matching stainless steel bracelet that integrates cleanly with the lugs. The overall construction provides a tangible sense of solidity and purpose.

Bulova's Marine Star collection often interprets nautical themes rather than strictly adhering to dive watch conventions. The reference 98A302 is a clear example, aimed at an enthusiast who appreciates a larger case and the visual intrigue of a mechanical movement. It is a piece for daily wear that carries a maritime spirit.

Its most defining feature is the open-heart display. Placing the escapement front and centre creates a dynamic focal point on the blue dial, a decision that prioritises aesthetic appeal over the sterile utility of a traditional tool watch. The 45mm Stainless Steel case reinforces this bold character.

A key consideration is the specification trade-off. The 100-metre water resistance rating is suitable for swimming, but this is not a professional diver. The choice of a Mineral Crystal over sapphire and the lack of ISO certification are practical compromises that keep the automatic movement accessible at its price.

This watch succeeds as a stylish and accessible mechanical piece. It offers the visual appeal of more expensive skeletonised watches in a robust, sport-inspired package. For those seeking a bold statement with a reliable mechanical engine, the 98A302 is a worthy contender.
