The Horizon is one of those bezels you really have to see in person.
Crafted from anodized aluminium, its character changes dramatically with the light. In some conditions, it can almost pass for a classic Pepsi; elsewhere, the red deepens into a rich fuchsia and the blue becomes a dark, almost navy tone. Then catch it at the right angle and the fuchsia suddenly flashes a vivid pink, while the blue comes alive as a beautiful, rich sea blue.
That variation is exactly why we chose it.
Rather than designing the Horizon around a single shade under studio lighting, we wanted a bezel with range — something that continually changes as you move your wrist and gives the watch a different character throughout the day. The warm gilt numerals tie everything back beautifully to the Black Bay's existing gilt detailing.
It's also why photographs never quite do this bezel justice. Depending on the light, two photographs of the same Horizon can look remarkably different. You really have to see this one on the wrist.
Available as a limited release, the Horizon is a fully reversible upgrade, allowing you to return your watch to its original bezel whenever you wish.
Wear it your way and discover a different Horizon every time the light changes.
