New 3120 Movement for 15400 - Concerns with Winding

[jojosnr]

Just sent my 15400 in for servicing because the date got stuck and the watch is dead. Service centre changed the movement to a new one.

Now I found that when I wind it, after one or two rotations of the crown, I can sense and hear a "Tsk" sound each time. ( as though the spring slipped)

Checked with the service centre and they say it is normal. I am not convince so would like seek some advice from experts here if anyone experienced this, and if all the new 3120 movements have this unique sensation.

Please advise. Thanks

If you can visit a local dealer with one on display, have a play with theirs and compare.
If it’s completely different, speak with APSC again.
Moreover, why did they exchange movements, rather than fix the one it was fitted with originally?

I had no idea why they changed the movement. Had the watch for three years without problems.

I will try to visit a boutique and try out as suggested. Thanks.
