GP calibre 3000/3100/3200/3300 automatic movement

December 8 2002, 8:22 AM 

GP introduced the in-house calibre 3000 and 3100 (quick-set date) in the Basel fair in 1994.
The movement family is basically very likely although the heigths is different due to the calendar on some movements:

3000 : 10-1/2 lignes, 2.98mm heigth
3200 : 10-1/2 lignes, 3.28mm heigth
3100 : 11-1/2 lignes, 2.98mm heigth
3300 : 11-1/2 lignes, 3.28mm heigth

It does have 27 jewels and a power reserve of 50 hours.
