Meridian - 12-Hour GMT Bezel (Compatible with Black Bay 58)

Introducing Meridian for the Black Bay 58

Striking, confident, and built for clarity – the Meridian bezel brings a bold new energy to the Black Bay 58. Its cobalt blue finish, paired with precision-engraved gold markings, captures the sharp contrast of vintage flight instruments while keeping a distinctly modern edge. Designed for maximum legibility and presence, it adds warmth and vibrancy without overpowering the watch’s balanced proportions. The result is a bezel that feels purposeful, contemporary, and effortlessly distinctive.

How a 12-Hour Bezel Works

Built around a 12-hour scale, the Meridian bezel transforms your Black Bay 58 into a practical dual-time watch. After setting your watch to your local time, rotate the bezel so the hour corresponding to your second time zone aligns with the watch’s hour hand. From that point on, the hour hand simultaneously indicates both local time on the dial and the secondary time zone on the bezel. As the watch continues to run, both time zones remain accurately tracked without further adjustment.

This system requires no additional movement complexity and works entirely mechanically, making it intuitive, reliable, and easy to use in everyday wear. While it does not distinguish between AM and PM, it offers a fast, legible way to monitor a second time zone - ideal for travel, remote work, or keeping one eye on home.

Fully reversible, the Meridian bezel allows you to return to your original bezel whenever desired, offering versatility with attitude.

Wear it your way and bring bold precision to your watch.
