A while ago, we posted some detailed photos of the LEMANIA calibre 1872 which was used by the giant manufacture GIRARD PERREGAUX. Today, we would like to introduce its even more complicated relative: the calibre 1883.
Look at the below images, clearly this is also a manual-winding movement, packing the chronograph function. Produced from around 1983, this calibre was widely chosen by some reputable brands such as SINN, ED HEUER & CIE., GERALD GENTA, and even OMEGA.
– 21600 vibrations per hour
– 17 or 18 jewels
– 40 hours of power reserve
– 27.5 mm wide
What makes this calibre 1883 more complex than the 1872 is the addition of date and moonphase complications at 12 o’clock. The usually-seen layout is that the moonphase sits inside the date ring, more importantly, the moon itself is decorated with a smiling face on the surface.
To adjust the 2 additional functions, there are 2 push buttons on the right side of the case. The higher one is for the moonphase and the lower one to correct the date.
Featured in some first images is our BAUME et MERCIER.
