Swiss watchmaker Marc Jenni has launched his own brand of watches, with the first being the Prologue. The watch is available in 18K white and rose gold, and uses the Marc Jenni Caliber 2010 movement. The movement looks like a base movement of some sort, though I’m not sure.

There are some modifications to the mechanism as there is no crown. Instead, the black rubberized ring that encircles the entire watch can be gripped and rotated. Rotating the ring either winds the watch, sets the time, or sets the date – depending on the setting, which is determined by pushing the button at 4 o’clock. The mode is indicated on the dial.

Quite an interesting watch, with a unique difference.
