Montblanc will unveil the new Star Twin Moonphase, along with many other new timepieces, at SIHH 2014 starting on Monday. The Star Twin Moonphase has a unique display that simultaneously shows the lunar phase (which is the sunlit portion of the moon, as seen from Earth) from both hemispheres. The moon looks different from Earth depending on which hemisphere you are viewing it from.

For example, if the moon curves to the left when seen from the Northern hemisphere, then conversely, it curves to the right from the opposite hemisphere. The Star Twin displays the moon phase in the Southern hemisphere with the blued steel hand and rings around the subsidiary dial at 6 o’clock. An aperture in the same dial shows the phase of the moon in the Northern hemisphere.

Fittingly, the dial features a wavy guilloche pattern. The hours are marked by black applied Arabic numerals. Blued leaf hands show the hours and minutes. The central seconds hand is blued and features a counterweight in the shape of the Montblanc star logo. Between 1 and 2 o’clock sits a date display with a blued pointed hand, with a crescent-shaped tip.

The 42 mm x 12.7 mm stainless steel case is fully polished, as is the ridged crown, which has a mother-of-pearl inlay Montblanc logo. The date and moon phase are adjusted via recessed pin pushers on the sides of the case. Sapphire caseback. The movement is a self-winding ETA with an add-on module. The Montblanc Star Twin Moonphase comes on a black alligator strap with a triple folding steel clasp.
