Bulova Marine Star: Sports watches water-resistant up to 200 m

Bulova Marine Star watches: sporting spirit, serious construction

Marine Star is the Bulova collection designed for those who live on the move and are looking for a watch that can keep up. From the dock to the city, from a weekend outdoors to the office desk: every reference is built with a tool-like attitude, designed to truly perform rather than just look sporty.

The design draws from the nautical world with functional consistency: diver-style rotating bezels to mark time intervals, screw-down crowns and case backs for superior sealing, and dials with high legibility even in difficult conditions. Water resistance ranges from 100 to 200 meters depending on the model, covering every need from daily use to more demanding water activities.

The collection offers three distinct souls to choose from:

• Quartz chronograph — integrated stopwatch function, practical and reliable for measuring time with precision
• Automatic — mechanical movement without a battery, with an exhibition case back on some versions to admire the caliber in action
• Precisionist 262 kHz — high-frequency quartz that guarantees superior precision and a second hand with a smooth, continuous movement

With generous 44 and 45 mm cases, refined finishes, and a value for money that sets Bulova apart in the segment, Marine Star is the choice for those who want concrete performance, a bold style, and daily versatility. Discover all available models in our catalog.

What movements are available in the Bulova Marine Star collection?

The Marine Star collection includes three types of movement. The quartz chronograph is the most practical choice, with an integrated stopwatch function for measuring time intervals. The automatic movement works without a battery, powered by the natural movement of the wrist, and on some models, it is visible through the transparent case back. Finally, the Precisionist 262 kHz is a high-frequency quartz developed by Bulova to offer superior precision compared to traditional quartz movements and a second hand with a particularly smooth motion.

How many meters of water resistance does a Bulova Marine Star have?

The water resistance of Marine Star models varies from 100 to 200 meters (indicated by the WR label on the technical data sheet). Models with 100-meter resistance are suitable for daily use, including splashes and short swims. Models with 200-meter resistance offer greater protection, also suitable for sporting water activities. It is important to always check the individual model's data sheet for the exact value and remember to fully screw down the crown and case back after every adjustment.

What is the rotating bezel on some Marine Star models used for?

The rotating bezel, inspired by professional diving watches, allows you to mark a starting point and visually measure a time interval. It rotates in one direction only (unidirectional) for safety reasons: even in the event of an accidental knock, the marked time can never be less than the actual elapsed time. It is useful not only in the water, but also in daily life to track cooking times, parking, workouts, and any time-based activity.

Who is the Bulova Marine Star collection suitable for?

Marine Star is aimed at those looking for a robust and versatile sports watch capable of transitioning effortlessly from physical activity to urban life. The generous 44 and 45 mm cases ensure a strong presence on the wrist and excellent legibility. It is an ideal collection both for those approaching the world of sports watches for the first time and for those who are already familiar with the segment and appreciate the value for money that characterizes Bulova.

What does Precisionist 262 kHz mean and why is it different from a normal quartz?

Precisionist is a proprietary Bulova technology. The number 262 kHz indicates the oscillation frequency of the quartz crystal, which is eight times higher than that of a standard quartz (32 kHz). This translates into two concrete advantages: much greater precision (with a very small annual variance) and a second hand that moves continuously and smoothly, without the classic "ticking" typical of traditional quartz watches. The result is a watch that combines the reliability of quartz with a visual experience closer to that of a mechanical movement.
