The Blancpain Villeret "Phase de Lune Demi-Savonnette" with a half-hunter hinged door case back.
This watch features:

• Polished 18kt rose gold case.
• Silver dial with a fine sunburst guilloche texture.
• Stylized applied rose gold Roman Numeral hour markers.
• Elegant rose gold leaf shaped skeletonized hour & minute hands.
• Large central seconds hand in rose gold.
• Complications:
  • Unlike most full calendar watches which have recessed pushers in the case edge & which require a tool to adjust the calendar features, this watch has the corrector buttons hidden beneath the lugs on the case back of the watch. This allows for a clean/uninterrupted look of the case edge & also the buttons can be activated with ones fingernails.
  • Also of note is that this Villeret model features a revolutionary method for adjusting the indications without fear of movement damage, allowing for complete date changes regardless of the time of day.
  • Day & Month windows displayed beneath the 12 o'clock position.
  • Date indicated by the blued curved hand which points to the current date. The ring area on the dial where the black date numbers are printed has a slightly different shade of silver.
  • Moonphase sub-dial located at the bottom of the dial.
• Blancpain Caliber 6654, composed of 321 components, contains 28 jewels & has an approximate power reserve of 72 hours.
• Solid 18kt Rose Gold hinged case back.
