[starystarynite]

I just gt a pre-owned sinn u2s. Is it normal to have the second hand nit movibg smoothly but yet keeping accurate time?

It is sometimes like shaking n not smooth when running. But one hr latr I check, time vry accurate.

Any idea wats going on? Or this is normal?

are you trying to say that the second hand is not advancing/sweeping smoothly aka like the second hand has a slight 'jerking' movement.

anyway, does this watch comes with warranty card that is stamped by local AD - The Hour Glass? if it is bought from THG but without warranty, you can send it to them to seek advice. however, if this watch is not bought from THG, then you can either choose to send it to sinn factory in germany on your own or ask THG to assist where they can charge you handling fees.
