On the occasion of Only Watch 2015, for the first time the Girard-Perragaux Vintage 1945 XXL Grand Date and Moon Phase features a rectangular-shaped DLC titanium case and a blue polycrystalline dial, one of the colours of the logo of the Monegasque Association Against Myopathies. A tribute to the charity auction, now in its sixth year, is the "Only Watch" signature on the caseback, through which one can admire the self-winding GP 03300-0105 manufacture movement (282 components, 32 jewels, 28,800 vibrations per hour, 46-hour power reserve). The indications on the dial are distributed as follows: jumping date at 12 o'clock, moon phase at 6 o'clock, hours and minutes in the centre with dauphine hands and applied Arabic and geometric numeral hour markers. The strap is black alligator with blue stitching and a DLC-treated steel folding clasp. This is a one-off.
