Dedicated to Hamilton's collaboration with the famous Air Zermatt air rescue service, this special edition features a highly readable black dial, with contrasting numbers and indices in blue Super-LumiNova®, which ensure maximum visibility even during night flights. The H-40 automatic movement, with an 80-hour power reserve, ensures that the watch is always ready to take off. With an enhanced power reserve of up to 80 hours, the H-40 stands out for its aesthetics and boldness. The 80-hour power reserve, almost double that of the market standard, allows you to remove the watch on Friday and still hear it ticking on Monday.
