The inspiration for this M34 F7 Semi Skeleton, with its mother-of-pearl dial and gradation, is the aurora: the curtain of colourful light floating in the night sky. The sapphire crystal with super anti-reflective (SAR) coating on both sides of the glass provides a clear view of the strong lines and shifting shades of the dial. The M34 F7 Semi Skeleton is powered by the automatic (with hand winding) in-house calibre F7F44 which provides high accuracy of 15 seconds to –5 seconds per day and power reserve of 50 hours. The movement with Geneva stripes and chamfer finish.
