3080 + 2003 = 30C0
G`day,
a nice example for GP?s fine detail work is the (former) GP 3080 automatic colum-wheel chronograph movement:

The new 2003 movement does have some improved details, like different levers and settings for the jewels.
Besides, some calibre numbers have slightly changed:
- The Foudroyante: GP E04C0
- The ww.tc: GP 33CO
- The Sea Hawk II: GP 33RO (unchanged)
- The Sea Hawk II "John Harrison": GP 33RO (unchanged)
- The "Ferrari F1" chronograph ref. 49560 and
the Richeville chronograph: GP 33C0
- The Ferrari "375MM": GP E03C0
- Watches with moon phase/big date: GP 3330 (unchanged)
Grande Classique ref. 49530
Richeville ref. 27600
Vintage45 ref. 25800
- The Flyback chronograph ref. 49580: GP 337A
- The Traveller II: GP 59G0
- The Vintage45 ref. 25930 (no date, small second at 6): GP 32P0
- The Vintage45 ref. 25960 (date at 6, small second at 9): GP 3290
- The Vintage45 "King Size" ref. 25830 (date at 2, small second at 9): GP 3390
- The Vintage45 chronograph: GP 30C0
- The Vintage45 "Power Reserve" ref. 25850 (date, small second at 9): GP 33R0
Of course, due to dials (like the different Sea Hawk II models) there are still different versions among the same calibre.
Greetings from germany,
