I’ve noticed that when activating the chronograph, the sweep second occasionally takes a few seconds to start. At other times the hand starts to move as soon as the pusher is pressed. Is this considered typical normal behavior for the El Primero?

 

Not had that problem on mine but it's only 4 months old. How long have you had yours and when was it last serviced?

 

Just recently serviced. I also recently acquired it so I’m unsure if it was doing it prior to service.

 

I would have expected it something they would correct it by default if it had been doing it before the service so I would send it back to have it solved.
