The difference between the 3330 and the 3337 is that the first has a solid case back and the second has a see through case back... Not a big deal, as the most interesting thing is the Front, here. And a marvelous one! Best, Nicolas ...
It really is quite a simple looking watch but just so beautiful at the same time, the finely finished dial with the subtle highlights of colour of the Breguet blued hands and the cheeky moonphase all just looks so good together. Marc
I wish Breguet made an exact reissue except at a slightly larger case size of 38 or 39 mm. The seconds subdial on the apparent reissue (ref. 7337) really breaks up the design perfection of the 3330/7. Cheers, John ...
