I would be very grateful for your input on how a vintage El Primero A385 should wind if it is working well. I have just purchased it but I am a little concerned that the movement is not winding correctly as while the crown turns anticlockwise very smoothly and easily, when I try to wind it upwards it is difficult and it feels like it grinding heavily so I am worried that doing so is damagaing it so I stop after a couple of turns. I understand from reading these forums that most El Primeros should wind in both directions so I feel it should not be experiencing such resistance when winding upwards as this would seem like the more normal direction for me to wind it. Would be interested on you thoughts on if this is normal or if there is an issue with the movement. Should it wind pretty freely both directions or is it normal for there to be considerably more resistance/grinding when winding upwards/clockwise?
May not be relevant but also setting the time seems somewhat stiff and jumpy when turning anticlockwise interestingly - although it does work I would expect it to be a smoother experience.
Thank you very much.
