It keeps the familiar burgundy-and-blue bezel, 41mm case, and true GMT functionality of the standard model, but the opaline dial changes the entire feel of the watch. The contrast is sharper, the overall look is brighter, and the watch feels more distinctive on the wrist than the original black-dial version.

The result is a watch that still feels unmistakably like a Black Bay, but with the added practicality of tracking multiple time zones. \u003cspan data-state=\"closed\" class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-end=\"3306\" data-start=\"2898\"\u003eThe opaline version gives that formula a different personality.
