HI, IS IT POSSIBLE TO KNOW WITHOUT OPENING THE CASE WHICH MOVEMENT IS FOUND INSIDE A BROAD ARROW (NO LONGER IN PRODUCTION) 3303 (HIGHLY DECORATED) OR THE MORE SIMPLE 3301? ARE THERE ANY PROBLEMS WITH THE LATEST 3301 AND 3303 MOVEMENTS (I KNOW THAT INITIAL... 

. . . please respond; I have no personal experience with any of these calibers, although at least one Omega thus fitted - the Constellation Double Eagle Mission Hills chrono - is on my shortlist. Thanks, Art

The initial 3301/3303 movements had problems but Omega has since resolved them. The calibre is several years old now and reliable. Mine had the 3303 and ran perfectly. It's a great movement and a good bang for the buck. - SJX...

is this: I have 2 Broad Arrows 3303 (In in steel and one in Red Gold for the 5 championship of M. Schumacher) both watches are incredible precise! and reliable, I have them for several years...and I have some of the new 3313 and are incredible precise too... 

From my understanding the caliber 3303 was fitted in the Brad Arrow, the 3301 version was used in "The Legend" (Schumacher) series for example...the caliber 3313 is based on the caliber 3303... Cheers! Monster
